00:00Hi kids! Today we will learn how to use division in our problems. So let's start!
00:12If John puts 30 pencils in 5 boxes equally, how many pencils will be there in each box?
00:24Here, John is asked to distribute or divide 30 pencils into 5 boxes.
00:34So he will divide 30 by 5.
00:40The quickest way is to just think, how many times 5 can go into the number 30?
00:51Think, 5 multiplied by what is less than or equal to 30?
01:00We get 5 times 6 equals 30.
01:06So, 5 can go into 30 6 times or 30 divided by 5 equals 6.
01:18You can also use long division method.
01:23Here, dividend is 30.
01:27Divisor is 5.
01:30Quotient is 6.
01:33Remainder is 0.
01:36That is, no pencil left.
01:41What we need here is quotient, which is 6.
01:47So, there will be 6 pencils in each box.
01:53Let's take another problem.
01:58If John puts 32 pencils in 5 boxes equally, how many pencils will be left?
02:10Here, John is asked to distribute or divide 32 pencils into 5 boxes.
02:19So, we will divide 32 by 5.
02:24And the quickest way is to just think, how many times 5 can go into the number 32?
02:35Think, 5 multiplied by what is less than or equal to 32?
02:45We get 5 times 6 equals 30.
02:52So, 5 can go into 30 6 times or 30 divided by 5 equals 6.
03:04And 2 will be the remainder.
03:08That is, dividing 32 pencils into 5 boxes, each box will contain 6 pencils.
03:18And remainder, 2, means 2 pencils will be left.
03:26You can also use long division method.
03:31Where 32 is our dividend.
03:35Divisor is 5 and quotient is 6.
03:42That is, each box will contain 6 pencils.
03:47Remainder is 2.
03:49That is, 2 pencils will be left.
03:54What we need here is remainder, which is 2.
03:59So, there will be 2 pencils left after division.
04:07If Ivy distributes 12 stickers into 3 groups, how many stickers will be there in each group?
04:19Here, Ivy is asked to distribute 12 stickers into 3 groups.
04:26And distribute means dividing.
04:30So, she will divide 12 by 3.
04:35The quickest way is to just think.
04:39How many times 3 can go into the number 12?
04:45Think, 3 multiplied with what is less than or equal to 12?
04:54We get 3 times 4 equals 12.
05:00So, 3 can go into 12 4 times or 12 divided by 3 equals 4.
05:11You can also use long division method also.
05:17Here, our dividend is 12.
05:21Divisor is 3.
05:24Quotient is 4.
05:27And the remainder is 0.
05:32What we need here is quotient, which is 4.
05:38So, there will be 4 stickers in each group.
05:43Now, let's take another example.
05:49Ivy has 20 apples.
05:53She wants to put 5 apples in one basket.
05:58How many baskets does she need?
06:03It is a repeated subtraction problem.
06:07That is, we need to find out how many times we can subtract 5 apples from 20
06:16to see how many baskets are required.
06:21And we learned that in every problem where repeated subtraction is required
06:28or distribution is required, we use division.
06:34So, we will divide 20 by 5.
06:40And we know the quickest way is to just think.
06:45How many times the divisor can go into the dividend?
06:51Think, how many times 5 can go into 20?
06:57Or, think, 5 multiplied with what is less than equal to 20?
07:085 times 4 equals 20.
07:13So, 5 can go into 20 4 times.
07:18Or, 20 divided by 5 equals 4.
07:25So, 4 baskets are required to hold 20 apples.
07:30If one basket must have 5 apples.
07:35You can also use long division method.
07:41Here, quotient 4 means 4 baskets required.
07:48Now, let's take another example.
07:52John has 40 colored markers.
07:57He wants to put 8 markers in one box.
08:01Then how many boxes does he need?
08:05Kids, it is a repeated subtraction problem.
08:11That is, we need to find out how many times we can subtract 8 markers from 40
08:20to see how many boxes are required.
08:25And we learned that in every problem where repeated subtraction is required
08:32or distribution is required, we use division.
08:37So, we will divide 40 by 8.
08:42And the quickest way is just think.
08:47How many times 8 can be subtracted from 40?
08:53Or, 8 multiplied with what is less than or equal to 40?
09:02We know 8 times 5 equals 40.
09:08So, 8 can go into 40 5 times.
09:13Or, 40 divided by 8 equals 5.
09:20You can also use long division method.
09:24And what we need here is the quotient which is 5.
09:30So, 5 boxes will be required.
09:35Good!
09:38So, what have we learned?
09:41We have learned wherever repeated subtraction is required
09:47or distribution is required, we use division.
09:53And you can solve division using any of the division methods we learned.
10:01Now, you may go ahead and take a quiz to learn more.
10:05Bye-bye!
