 capaciteer is de hoek van liquid dat de container kan uit wat je over daar zie, is vier containers elk van die is markt met de capaciteer van 1 liter nou kan je snel uitleggen hoeveel marks doe je op dat container 8 marks 1, ek zei dat 1, 1 mark is equal te de capaciteer van 1 liter wat is de capaciteer van die hoek van 8 liter water we gaan nu een klein rast gaan en ek snel wil jou uitleggen als je die bagen moet uitleggen, die cans moet je estimatie wie het is, moet je met actieel, waar moet je estimatie zien wat liter, wat bottles je wil gebruiken, om die te uitleggen wat denk je, wat is de capaciteer van dit bottle het is 2 liter en dit is 5 liter en hier hebben we nog een klein one 500 mililiters en dan hebben we hier 1 liter bottle dus je moet nu dit bottle uitleggen en je moet uitleggen hoeveel van dit bottles je moet uitleggen dit bagen dus ek geef jou een klein beetje tijd om te snel uitleggen en dan luister jou en als je klaar is, vertel me ok? 1, 5 liter en 3, 2 liter bottles om die container te uitleggen rast, je is allemaal ver, het is maar 1, 1, 4, 5, 6, 7, 8 je is ver ok, die van jou heb nou uiteindelijke containers we gaan nu ons rast gaan dus toen ek zei, ek kom op 3 en ek zei, go, dan begin je te rast ok, 1 container in die tijd 3, 2, 1, go dat is wat mathematiek is allemaal over Hulani, kom hier, geef al die kool in between wat gaan ouders, dit is program 3 in ons mathematiek videoleerning serie voor grade 6 leerners vandaag doen we het om de estimatie en de measurement van de capaciteit na wat dit luister, moet u die able te estimatie en de measure capaciteit konvert between de s i unit van de simulatatie kompane oor de capaciteit measurement en ronde van de capaciteit dit is jouw kans om de capaciteit measurement te onderstaan once en vooral, dus geef jouw opende notebook grade gelijk en geniet van het program actie, ek vervies het, ek denk dat dit van de seguret het, maar vervies het op jou kurs, weet u de capaciteit van een kaap? mililiters of cooling do you think each cup we measure volume in mililiters and liters right and those are the s i units for volume s i units what are you to talking about jane is talking about we call the quantity of liquid a container can hold its capacity the units of capacity are mililiters liters and kiloliliters it's correct i am pulani how many cups did you use to finish that one liter four cups very good pulani that means that four times two hundred and fifty mililiters equals one liter okay there's a thousand mililiters in a liter once again pulani we use potters and containers to look particular again she bakes using a teaspoon well i do not think that susan would have problems in this area of mathematics and when it comes to exam times she will be the one laughing please susan tell us thank you susan we have your classmates here to say that mathematics is everywhere in real life and not only textbooks look at these two potters they each hold 500 milliliters and when the content of these two potters are put together they can fill up a one liter bottle like this one liter is equal to four two hundred and fifty mililiters glasses and also two five hundred mililiters that is correct and the liquid in two cups can fill a five hundred mililiters bottle and that's equal to half a liter girls it's go home it's hot here in the sun girls before you go and get this let's continue the conversation let's talk about kilometers yes what will hold so much liquid jay you'd be surprised an average family car holds about 50 liters a 20 cars will hold approximately one kilometer of a truck how much field do you think these big trucks hold that transport petrol and diesel ah okay i see we measure such large quantities of capacities like the amount of fuel in the large fuel transport trucks in kilo liters is that right that's exactly right one kilo liter is equal to a thousand liters can you think of more examples of fluids measured in kilo liters um maybe the amount of water in a big damn units either in exam or in real life it's very important to make sure about the volumes there's a big difference between milliliters and kilo liters viewers let's convert between the different units of capacity we have seen that one milliliter is 1000 part of a liter en one liter equals a thousand milliliters one liter equals a thousand part of a kilo liter and one kilo liter equals a thousand liters when we convert from a large unit of capacity to a smaller unit of capacity we must multiply by a thousand for example when we convert liters to milliliters en kilo liters to liters mille means a thousand remember how we say the millipede has a thousand feet even thou this is not strictly true this is useful to remember when we convert units let's apply this to a mathematical problem we have to convert seven liters to milliliters one liter is a thousand milliliters right so seven times a thousand is seven thousand milliliters let's do another one we have to convert eight point two three five liters to milliliters well this is not difficult we just shift the digits three places to the left en our answer is 8 235 milliliters now remember that as we multiply to convert from a larger unit to a smaller unit we should now do the opposite when we convert from a smaller to a larger unit let's look at the rule when we convert from a smaller unit of capacity to a larger unit of capacity we divide by a thousand let's convert 2000 milliliters to liters 2000 divided by a thousand gives us that's right two liters how about another one 4567 liters convert to kilo liters okay we know that the rule says divide by a thousand to get a larger unit right so we simply move the digits three places to the right and we get our answer 4.567 kiloleters juus yes it's the same as 2000 milliliters okay but if a two liter is equal to 3000 milliliters how much is it equal to no guys that's not so big if two liters is equals to 2000 milliliters then one liter is equal to 1000 milliliters that means the half liter is equal to 500 milliliters now where does that come from oh i see we should remember with the big one liter bottle daily it can hold four cups or two five hundred liter bottles yes then a quarter of a liter ten equals to two and a quarter mililiters oh you guys i'm with my native breakfast and i see you guys viewers we will now round of capacities just as we did rounding of in whole numbers we can now round of capacities let's quickly revise the rules for rounding of whole numbers to the nearest thousand when we round of numbers to the nearest thousand we look at the value of the hundreds if that value is 500 or more we round up if the value is less than 500 we round down for example if we round of 600 to the nearest thousand 600 is more than 500 so we will round up to 1000 now on the screen you can see four jugs of water let's round of the capacity in each in jug one 545 milliliters to the nearest 10 milliliters in jug two 339 milliliters to the nearest 10 milliliters in jug three 950 milliliters to the nearest thousand milliliters en in jug four 240 milliliters to the nearest 100 milliliters we are done learners it is good that you still remember what you've learned in the first trimester we are now going to look at how to round off when we have different units of capacity don't worry the same rules as before apply let's round off seven liters 356 milliliters to the nearest liter when we round of the nearest liter the milliliters must be 500 or more than 500 for us to round up if the milliliters are less than 500 the liters will stay the same it will not increase this is the case here 356 milliliters is less than 500 so we round down and the answer will remain seven liters let's do another one we have to round off 12.879 kilometers to the nearest kilometer we now look at the digit behind the decimal sign if that digit is five or more than five in other words 56789 we round up let's see the digit behind the decimal sign is eight so we round up and our answer is 13 kilometers and a last one 12.178 kilometers round off to the nearest kilometer we now know that if the digit behind the decimal sign is zero one two three of four we round down so the digit behind the decimal sign is one in this case which means we round down and our answer is 12 kilometers oh Mary i'm so impressed you children learn a lot in school these days um in the we never learn by by by this grade if i can recall correctly but Mary to answer your question yes we can use rounding of when we want to add larger numbers in some situations like when you when we are doing calculations in our heads we do not need to use the exact values we can round off to any any number depending on the level of accuracy we need let me show you let me show you 545 milliliters plus 950 milliliters plus 240 milliliters plus 339 milliliters we can round off the numbers to the nearest 10 and then add so we'll say 550 milliliters plus 950 milliliters plus 240 milliliters plus 340 milliliters and we get 2800 milliliters that's right or to the nearest 100 and add and then it will be 500 milliliters plus 1000 milliliters plus 200 milliliters plus 300 milliliters why do we get Mary i think it's 2000 milliliters then okay now we can round off to the nearest 10 and 100 and then add this gives us 550 milliliters plus 1000 milliliters plus 200 milliliters plus 340 milliliters and the answer is looks like 2040 milliliters viewers we have come to the end of lesson 3 it's time to summarize what we have done we call the amount of liquid a container can hold its capacity there are different units of capacity milliliters liters and kilo liters we can also convert between different units of capacity one liter is a 1000 milliliters one kilo liter is equal to a thousand liters one milliliter is equal to 0.001 liters one liter is equal to 0.001 kilometers there are rules that we have to follow when we convert between different units of capacity for converting from a larger to a smaller unit of capacity we multiply by a thousand when converting from a smaller unit to a larger unit we divide by a thousand we have also looked at comparing and ordering of capacities capacities can also be rounded after the nearest appropriate units viewers we trusted you now know almost everything about capacity we look forward to having you in program 4 again until then keep well
