Doing Math with Metrics

Show Transcript

are you guys welcome back to another math Bridge lesson they were talking about doing math with metrics so we can talk about the metric system for the past couple of days getting to understand it if not with the fixes different quantities and appropriate tools for measuring different things such as Lane time distance waves and such and such a week and do some math with it herb Jackson today is to use addition subtraction multiplication division of metric measurements to solve real-world problems okay so they want us to always reduce our answer to the smallest units click on the conversion charts below to see the values of different okay don't reminder standing for example does minor saying right if the answer was for example not not that this is a metric unit at all but understanding of this would be like if the answer was one day they want us to reduce it to how many minutes that is that's why I said let's see when you guys if you guys have your phones out and I ran out a picture of this she has to have it for real for reference this is in relation to the distance or this would be weights volume smallest unit alright okay give us some examples so you can see what they mean by smallest unit so now we begin doing some math using measurements adding metric measurements to be sure the measurements you add are same time example you cannot add Desi G to CG so, so they want us the kind of like when we're doing addition or subtraction of fractions they want the same denominator kind of like I guess an example could be like if you're adding money up they wouldn't want his adding dollars with coins even though we totally could do that right they want us to converted all 21 unit of measurement for example all coins and then added up together right really blood save if we were doing measurements in Heights make it all inches and add it all together but in real life that you can you can add things of different measurements right I can for example take I don't know I can take a a pound of beef and then by 4 oz of beef I have a lb and 4 oz even though one is in pounds the other ones announces but that's perfectly fine I wouldn't have to say oh I have 20 oz of beef a pound and a quarter of beef okay this one we can't do this one yeah but this this is you know this is not have customary and metric my gal gal is what we're used to write you know it's on a different scale so that's why you know you can't combine those two together it's like what the temperature right now in Psych let's see if it's 0 degrees C two more degrees Fahrenheit to that you can't you first have to convert over to Celsius not compatible with one another right I don't like saying I'm going to put some gasoline in my electric car or I'm going to plug my gasoline car into the wall and charge it up they don't mix so I was let you go to the school start the clerk's fill the shelves with the latest shipment of motor oil the oil comes in three different sized containers when is measured in dal 1 + L + 1/3 + DL inventory is taken twice a day when the store opens and again when the store closes Cemetery table below to answer the phone question so let's see what the question is what is the total amount of motor oil in the store when it opened in dal and you need to convert the car l in DL containers it'll be all right so busy they want to maybe she wants to add these three numbers up and convert to a Dal so now comes the conversion Park let's just Dal Rae oh that we have 54 of the leader you have 65 but we need to see what that converts to does anyone recall how many liters are in a dekaliter 1010 perfect so in this case if if 10 L equals 1 Dal I would take my current amount of leaders in / 10 to figure out how many decaliters are in 665 and 10 / 10 5/6 now it's take care of the DL so how many deciliters do I need chewy to try to get to a 1 L play me Panda c l 2 gets one way to get one time I go from Jessie 2 L how many 10 deciliters equal 1 equal 1 Dal so if each one is is increasing tenfold so let's use the the DL I have 74 in terms of L that would be 7.4 l and then if I were to convert from L to decaliters that would be 74 Dal and now I can add up all of my numbers to go 54 + 6.5 + 2.74 the princesses and the whole numbers so my whole numbers are 54 and and and six rights that be 60 and now I have to add the 50 think of it in terms of money that's easiest $0.50 + 74 survive 50 and add 270 for 50 Cent of that 74 is going to form a dollar and then I'm going to have $0.24 left over right so that's going to bump that 6261 and before I submit it let's just ask if they want any rounding no they don't mess around anymore what's going on okay good so we got it right now let's all look at that I'm going to recap the explanation so that you know so that we're all on the same page as to how we got here so the first thing I do is I just read copied on my measurement 1 Dal 54 16051 DL 74 so I have all my quantities written right I don't have to alter anything to the Dal right because that's the the unit that they want to answer them so Dal is fine 54 that doesn't change so then I focus my attention on the 2nd regiment 65 so you know one of the things that if you forgot my call how much is in a dekaliter over there you can think of other words that have that have that have that prefix for example a decade maybe you know how many years are in a decade decade when by 10 years sometimes I like to make jokes and be like let's say someone is 10 years old and my father decade-old wrightsock sounds much older than 10 years sounds a lot older than 25 it is a prefix Dal decade 10 if we're going from smaller to larger meaning l two. we're going to take that first word smaller that's what's going to happen to America value and we know that's going to happen tenfold so that means I'm going to move the decimal point over one place to the left so from 6500 to 6.5 and that's if I go down to next for the next one I'm going to have to do two conversions the first one is going to be from DL to L and that's going to be tenfold smaller the numerical value so 74 I take the decimal when I move it one spot over that becomes 7.4 now I'm at L I have to make one more Judgment of the decimal to left and now I'm at Dal did I take all my values on the far right 54 + 6.5 + 2 + 74 + what is the total amount of motor oil in the store when it closed in dal so is there anyone who wants to guide me through this one just instruct me the closest one is in one volunteer or at least or even if you're not sure from start to finish just got me through as far as you can Dal leader it says 1 liter container so change how much is 1 L in a dekaliter the amounts to DAL I need a hug it all in dal right okay perfect yeah so that's my first step I need to convert the the 18 L into decorator so what would that look like if I were to convert what number would that be it would be * 10 it would be divided by 10 so we're going to L to decaliters sounds are going from smaller to larger smaller to larger units sold that first word that we said smaller that's what's going to happen to our numerical value of a smaller so what do we do to a decimal when we divided by 10 which direction is a move to the left or to the right the last so this 18 becomes what number 18 it's only going to move one space to the left so it's going to be come with 1.8 now do you remember what to the DL how many spaces do I move that number over after the decimal point how many faces that move that over on the previous one on page what's the question now we're looking at the DL right that has 36 DL question is how many times am I going to move the decimal point over to the left in order to convert from DL to DAL 2.36 perfect so now I can add these numbers up to get right no out of the whole numbers first 11 + 1 is 12 and then silver coins right $0.80 + 3620 of those scents from the 36th are going to help me form a dollar for this 12 is going to go up to 13 now I have the remaining $0.16 from the $0.36 so this would be 16 and there's no mention of any money we're just talkin oil here but again when one can I see decimals I just think of coins right cuz that's yeah that's the most common place I see decimals right is when your grocery shopping or whatever you know so that I can get it but you can whatever makes the most sense for you great job thank you so much for the help okay the clerk fill the shelves with the latest knock at the same store oils sold on this particular day in dal okay do we have to first- the yes first we need to do a subtraction yes very good so let's see what our numbers are so what am I going to get here for the Dal containers how many were sold 43 43 how about for the L continuous how about for DL 38 okay so that was step number one you know problem how many did they have at opening second problem, do they have a close third problem how many do they sell they don't tell us how many they sold so we need to realize that oh that's on us to figure out how do you figure out is by subtracting opening inventory from the closing inventory not to let us know how many were sold okay so great now we have the quantities so all right someone give me some guidance. That was the first step what what am I going to do next what I do I can but if someone else once they go alright thank you do you want to go ahead and share when you change the leader and it DL into a dekaliter so what would my leaders become if it's currently 47 m would it be as Dal 47 point 4.47 or 4.7 one of those I'm not sure which way 3 + 4.7 so I'll give you guys a hint when we went if you're if you remember on the other two problems the conversion was the same when you go from liters to deck you move the decimal one spot two left so how many spaces we move for the DL am I moving the best with your leader is that what I'm doing how many parking spaces would move to the left so now that you guys know that I mean the problems may change in the future but that that's the one you thing that you guys have seen today is now whenever you guys do the conversion L to decaliters just take that decimal point movie one over if you have DL to over so now like if if they keep showing us the same problem you know how about a I have that thought Remembered in your mind right that oh if you go you know if you go from L to Becca one over from Desi to dekha to over and then it becomes kind of marvelous Marv a habit you know you see it in you kind of just converted the whole numbers first 43 + 447 and then let's look at the coins as I call it $0.70 and thirty-eight cents will if I take the $0.30 from 38th and added to the 70 that's a dollar so that means on 47 goes up to 48 just left with $0.08 explain to myself and in a lot of this we're doing right now is also going to come in handy for your science test so science you know you can't have science look up when over right now is also going to come in handy with with the science test is a science test have a math component to it and especially like it sets of questions about conversions and stuff like that that's totally closer to the science test Realm especially this question to him and yells doctor recommends that she gets one gram of calcium a day if the nails yogurt contains 250 mg of calcium how much more does she need our daily requirement okay so let me ask you guys this is anyone know how many milligrams are in 1 G how much is an ounce a thousand a thousand so she has 250 mg already in her yogurt how many more milligrams does she need to consume that whole gram 3 I mean from it's either 700 7:50 or 7:25 which one is how many more does she need what amount would she need Sunset 750 okay multiplying measurements okay when you do multiplication using measurements you remember to do the following what's B measurement class separately by the multiplier for example 6 * 3 50 cm * 3 all right and the whole reason I were doing that is because you know we need to differentiate between the units right if we were to have a let's see what we would get if we if we just did 6.5 to get it like 61 56.5 * 319.5 and if you were to do that you you would think okay what's 19 M and 50 cm yeah you did the wrong answer so we have to separate based on John's Car average is 9 km what is 4 L of gas I mean kilometers can drive with 22 L of gas in his car all right the trailer went out let me know how far can you drive 98 how much is a 198 this is the distance that a travel each leader right do we have 22 of those leaders who does x x 9 figure out the total distance all right and then division okay you just bought a truck load of coal to heat your rental homes for the Winter Ski season I'll look at us huh everyday stuff we do the truck can carry 7474 kilos of coal at a time how much cool home get if you divide the truckload equally among 16 homes if a decimal rounded to three decimal places how much coal will each friend get okay so all they're asking is what is this number divided by that number. 467.125 but then we need a round it rounded to three decimal places this is the first second and third it's weird that they even say rounded to 3 decimal precise answer your there's no rounding here okay this truck carries a little bit more call and now we have 17 ski resort homes so 351.588 because it turns into number that is 6 after the decimal all right lighter truck load 4593 us-17 7 is 67 right give a decimal answer who got drawn into last place the flower we don't even get a decimal them a water bottling company has purchased the rights to bottle 1364 of spring water a month from the local spring how many one liter bottles can a produce always found that interesting like when you let's say you buy Evian water and it says oh this Waters from the French Alps yeah I kind of Wonder I'm like so do they have it just like these planes characters flights from France to all over the world just constantly be flying planes filled with plane loads of water and then they just no it just seems kind of when they say a month every month has a different amount of numbers Estates right yeah but it's true but each month regardless of what month has the ball of the same amount even feels like a 28in in this problem so how many 1l bottles can they produce a month 2364 it's like that question I used to be a viral video that guy was a guy ask another guy if you travel 60 miles per hour how far will you go if you drive for 60 minutes all right water bottling company has purchased the rights to bottle 1992 of spring water from a 4 liter bottles can they produce in a month are we multiplying or dividing or 98 yeah the reason we're dividing his because each bottle is for leaders who would have to take for a we have to remove for leaders from the total each time so we divide the total number L by 4 to let us know how hey sending 873 descendants 2 L bottles what are you what are you guys got is going to go home if anyone else has the insert date if John has a then we have it I'm going to put 4:36 because that point by would be if it's half a bottle then it's one less but they're asking how many 2 L we could produce okay all right since a bottle ask how many two-liter bottles can produce the remainder of half a bottle is not use cuz I'll be one leader the company can produce 436 total fool 2 L bottles so contacts matter you know what they're asking if this was like again if this was money you know the employee of the year bonus was 800 some $3 and it was going to be split evenly amongst two employees how how much is each employee going to get for the bonus will there to be $436.50 but if each bottle has to be to what am I can't count the 50s the context matters all right
