Dividing by 10

A decimal point comes after a whole number e.g. 2.1 - the number two is a whole number.

Move the decimal point one place to the left.


Example 1

2 ÷ 10 = ?


Before
ThHTU1/10
2
After
ThHTU1/10
2


Answer= 0.2




Example 2

30 ÷ 10 = ?


Before
ThHTU1/10
30
After
ThHTU1/10
30


Answer= 3




Dividing by 100

Move the decimal point two places to the left.


Example 1

750 ÷ 100 = ?


Before
ThHTU1/101/100
750
After
ThHTU1/101/100
750

Answer= 7.5




Dividing by 1000

Move the decimal point three places to the left.


4000 ÷ 1000 = ?


Before
ThHTU1/101/1001/1000
4000





After
ThHTU1/101/1001/1000
4000

Answer= 4





Dividing Numbers


If you know your times tables the following divisions will be easy for you to calculate:

Example 1

42 ÷ 7 = ?

We know 6 x 7 = 42.

Therefore 42 ÷ 7 = 6.


division

Example 2

32 ÷ 8 = ?

We know 4 x 8 = 32.

Therefore 32 ÷ 8 = 4.


division
