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.
4 000 ÷ 1 000 = 4
32 000 ÷ 1 000 = 32
50 000 ÷ 1 000 = 50
