1.8 Division

Division by 10, 100 and 1 000

÷ 10

To divide a whole number by 10 (when the number ends in a zero), remove a zero from the end of the number to make it 10 times smaller. For example:

20 ÷ 10 = 2

60 ÷ 10 = 6

100 ÷ 10 = 10

÷ 100

To divide a whole number by 100 (when the number ends in at least two zeros), remove two zeros from the end of the number.

300 ÷ 100 = 3

2 500 ÷ 100 = 25

6 000 ÷ 100 = 60

÷ 1 000

To divide a whole number by 1000 (when the number ends in at least three zeros), remove three zeros from the end of the number.

000 ÷ 1 000 = 4

32 000 ÷ 1 000 = 32

50 000 ÷ 1 000 = 50
