Kali is having a picnic for her six friends.
0:00:04.021,0:00:06.842
The oldest friend, Vikram, is 10 years old.
0:00:06.842,0:00:09.907
The youngest, Diya, is six years old.
0:00:09.907,0:00:12.020
She has a total of 48 blueberries
0:00:12.020,0:00:13.808
and wants to split them evenly
0:00:13.808,0:00:15.480
between her friends.
0:00:15.480,0:00:18.928
How many blueberries does each friend get?
0:00:18.928,0:00:20.019
And I encourage you to now,
0:00:20.019,0:00:21.307
pause this video
0:00:21.307,0:00:22.688
and try to figure it out on your own.
0:00:22.688,0:00:26.763
How many blueberries does each friend get?
0:00:26.763,0:00:28.226
Let's think about this a little bit.
0:00:28.226,0:00:30.606
So she has six friends.
0:00:30.606,0:00:31.684
She has six friends
0:00:31.684,0:00:33.438
and she wants them all
0:00:33.438,0:00:35.587
to be able to get the same amount.
0:00:35.587,0:00:38.721
So, she wants to split the 48 blueberries evenly
0:00:38.721,0:00:39.939
amongst her six friends.
0:00:39.939,0:00:42.145
The ages of her friends don't matter.
0:00:42.145,0:00:44.689
So, she's going to take the 48 blueberries.
0:00:44.689,0:00:46.661
She's going to take the 48 blueberries
0:00:46.661,0:00:48.565
and divide it,
0:00:48.565,0:00:50.237
and divide it
0:00:50.237,0:00:51.305
by six.
0:00:51.305,0:00:53.882
She wants to divide it into six groups.
0:00:53.882,0:00:57.806
So she wants to divide it into six groups.
0:00:57.806,0:01:00.337
48 divided by 6.
0:01:00.337,0:01:01.713
And so this,
0:01:01.713,0:01:03.065
so question mark,
0:01:03.065,0:01:06.060
is going to be equal to the number of blueberries
0:01:06.060,0:01:08.834
that each friend gets.
0:01:08.834,0:01:11.922
So 48 divided by six is equal to question mark,
0:01:11.922,0:01:13.954
is the same thing as saying
0:01:13.954,0:01:16.044
that 48,
0:01:16.044,0:01:18.621
48 is equal to,
0:01:18.621,0:01:23.044
is equal to question mark times six,
0:01:23.044,0:01:24.623
times six.
0:01:24.623,0:01:25.760
So if we could figure out
0:01:25.760,0:01:28.117
what number we can multiply by six
0:01:28.117,0:01:29.813
to get 48,
0:01:29.813,0:01:32.598
then we know what 48 divided by six
0:01:32.598,0:01:33.921
actually is.
0:01:33.921,0:01:35.361
For example, this question mark,
0:01:35.361,0:01:37.416
this is the number of blueberries per friend.
0:01:37.416,0:01:41.653
The number of blueberries per friend times six friends,
0:01:41.653,0:01:43.777
well that should tell us the total number of blueberries,
0:01:43.777,0:01:45.542
which is 48.
0:01:45.542,0:01:47.562
So what is this number?
0:01:47.562,0:01:48.560
Well, let's think about,
0:01:48.560,0:01:49.512
let's just think about
0:01:49.512,0:01:51.857
all of the multiples of six.
0:01:51.857,0:01:56.177
So, six times one is equal to six.
0:01:56.177,0:01:59.357
Six times two is equal to 12.
0:01:59.357,0:02:02.178
And really we're just increasing by six each time.
0:02:02.178,0:02:04.534
We're just increasing by six.
0:02:04.534,0:02:07.878
Six times three is equal to 18.
0:02:07.878,0:02:10.954
Six times four is equal to 24.
0:02:10.954,0:02:15.099
Six times five is equal to 30.
0:02:15.099,0:02:18.697
Six times six is equal to 36.
0:02:18.697,0:02:21.495
Six times seven is equal to 42.
0:02:21.495,0:02:23.573
Notice we're just adding six every time.
0:02:23.573,0:02:27.834
Six times eight is equal to 48.
0:02:27.834,0:02:29.993
Is equal to 48.
0:02:29.993,0:02:32.350
So we now know that question mark,
0:02:32.350,0:02:35.948
we now know that the question mark must be eight.
0:02:35.948,0:02:36.889
Six times eight
0:02:36.889,0:02:38.793
and eight times six is the same thing.
0:02:38.793,0:02:40.155
So this is going to be equal
0:02:40.155,0:02:42.716
to six times question mark.
0:02:42.716,0:02:46.408
Six times question mark
0:02:46.408,0:02:47.569
and now we learned
0:02:47.569,0:02:50.332
that question mark is equal to 48.
0:02:50.332,0:02:53.246
Sorry, question mark is equal to eight.
0:02:53.246,0:02:54.407
So, each of her friends
0:02:54.407,0:02:56.473
are going to get eight blueberries.
0:02:56.473,0:02:57.588
So this is, right over here,
0:02:57.588,0:03:02.588
48 divided by six is equal to eight blueberries.
0:03:03.973,0:03:05.807
Now, let's verify that.
0:03:05.807,0:03:08.233
We have 48 blueberries right over here.
0:03:08.233,0:03:10.474
Lets divide them into six groups
0:03:10.474,0:03:13.852
where each group is going to have eight blueberries.
0:03:13.852,0:03:15.024
So let me do my best.
0:03:15.024,0:03:17.385
So let's see, this is one, two,
0:03:17.385,0:03:22.385
three, four, five, six, seven, eight.
0:03:22.930,0:03:25.426
So, that's a group of eight blueberries.
0:03:25.426,0:03:28.630
See, here's another group of eight blueberries,
0:03:28.630,0:03:30.627
right over here.
0:03:30.627,0:03:33.610
And there's another group, right over here,
0:03:33.610,0:03:35.944
of eight blueberries.
0:03:35.944,0:03:37.929
And then, here's our fourth group
0:03:37.929,0:03:40.193
of eight blueberries.
0:03:40.193,0:03:40.912
And now, let's see,
0:03:40.912,0:03:43.052
we can make a fifth group
0:03:43.052,0:03:45.544
of eight blueberries.
0:03:45.544,0:03:47.425
Fifth group of eight blueberries.
0:03:47.425,0:03:48.390
And then, finally,
0:03:48.390,0:03:50.722
here is our sixth group.
0:03:50.722,0:03:51.987
Here is our sixth group
0:03:51.987,0:03:54.031
of eight blueberries.
0:03:54.031,0:03:54.729
So notice,
0:03:54.729,0:03:56.921
we have six groups of eight blueberries.
0:03:56.921,0:03:58.349
Each of her six friends
0:03:58.349,0:04:00.160
could take one of these groups
0:04:00.160,0:04:01.873
of eight blueberries.
