- We don't but they just put that information to trick you(2 votes)

- what if there is an odd number like 49 do you put it like 1.5(1 vote)
- Great question! This is an example of
**dividing with a remainder**. Sal gives an example with 6 friends. If you were to divide 49 blueberries evenly amongst 6 friends, you would still get 6 groups with 8 blueberries in each group, which would still come to 48 blueberries,*but now you have 1 extra blueberry*left over! This extra blueberry is the**remainder**. You could then go on to divide the remaining blueberry into 6 equal parts so that each group contains 8 blueberries + 1/6 of a blueberry. Though I think it might be difficult to cut a blueberry up that small, so I would leave it as 6 groups of 8 blueberries with 1 blueberry as the remainder. Hope this answers your question!(1 vote)

- help me and why(1 vote)
- Does the question mark equal eight?(0 votes)
- Yes because 48 divided by 6 is 8 and 6x8 is 48(3 votes)

- HI PEMAAAAAAA btw this idea is dooo goood THANK YOU FOR TELLING US SHRANG KOU(1 vote)
- this is perfect for kids THANK YOUUUUU(1 vote)
- Why berries and friends.(0 votes)
- Why would he go throw 6's to see what the answer is? Why can't he just draw an rectangle and put 8 on the top because it the longest. And put an 6 on the side because it is short . the when he done he can just use multipy them to get the answer.(0 votes)
- But we're not looking for 6 times 8 = ?. In this problem we're looking for 48 divided by 6 = ? We're not looking for the total 48, we're looking for the multiple 8. You have to divide, not multiply.(2 votes)

- ya what are the ages for what he said(0 votes)

## Video transcript

- Kali is having a picnic
for her six friends. The oldest friend,
Vikram, is 10 years old. The youngest, Diya, is six years old. She has a total of 48 blueberries and wants to split them evenly between her friends. How many blueberries does each friend get? And I encourage you to now, pause this video and try to figure it out on your own. How many blueberries does each friend get? Let's think about this a little bit. So she has six friends. She has six friends and she wants them all to be able to get the same amount. So, she wants to split
the 48 blueberries evenly amongst her six friends. The ages of her friends don't matter. So, she's going to take
the 48 blueberries. She's going to take the 48 blueberries and divide it, and divide it by six. She wants to divide it into six groups. So she wants to divide it into six groups. 48 divided by 6. And so this, so question mark, is going to be equal to
the number of blueberries that each friend gets. So 48 divided by six is
equal to question mark, is the same thing as saying that 48, 48 is equal to, is equal to question mark times six, times six. So if we could figure out what number we can multiply by six to get 48, then we know what 48 divided by six actually is. For example, this question mark, this is the number of
blueberries per friend. The number of blueberries
per friend times six friends, well that should tell us the
total number of blueberries, which is 48. So what is this number? Well, let's think about, let's just think about all of the multiples of six. So, six times one is equal to six. Six times two is equal to 12. And really we're just
increasing by six each time. We're just increasing by six. Six times three is equal to 18. Six times four is equal to 24. Six times five is equal to 30. Six times six is equal to 36. Six times seven is equal to 42. Notice we're just adding six every time. Six times eight is equal to 48. Is equal to 48. So we now know that question mark, we now know that the
question mark must be eight. Six times eight and eight times six is the same thing. So this is going to be equal to six times question mark. Six times question mark and now we learned that question mark is equal to 48. Sorry, question mark is equal to eight. So, each of her friends are going to get eight blueberries. So this is, right over here, 48 divided by six is equal
to eight blueberries. Now, let's verify that. We have 48 blueberries right over here. Lets divide them into six groups where each group is going
to have eight blueberries. So let me do my best. So let's see, this is one, two, three, four, five, six, seven, eight. So, that's a group of eight blueberries. See, here's another group
of eight blueberries, right over here. And there's another
group, right over here, of eight blueberries. And then, here's our fourth group of eight blueberries. And now, let's see, we can make a fifth group of eight blueberries. Fifth group of eight blueberries. And then, finally, here is our sixth group. Here is our sixth group of eight blueberries. So notice, we have six groups of eight blueberries. Each of her six friends could take one of these groups of eight blueberries.
