Arithmetic Grade Three

Lesson One hundred twenty-four: Division Patterns

Study the following division problems. 


	8 ÷ 4 = 2

        80 ÷ 4 = 20
You should notice that the number of zeroes in the first number and the answer remains the same and that 8 divided by 4 remains 2 regardless of the number of zeroes involved.

Here's a slightly more complicated example. 


       63  ÷  9  =  7

       630  ÷  9  =  70
You can see that the number of zeroes in the first number and the answer remains the same and that 63 divided by 9 remains 7 regardless of the number of zeroes involved.

Here's a slightly tricky example: 


        20  ÷  5  =  4

        200  ÷  5  =  40
Remember that when in doubt, you can always check your answer with multiplication. 

        4 x 5 = 20

        40 x 5 = 200
