In this activity, you will practise dividing numbers by 2, 4 or 5 in your head.

Divide by 2          Halve the number

Divide by 4          Halve and halve again

Divide by 5          Double the number and divide by 10

Examples

5.64 ÷ 2 = 2.82

5.64 ÷ 4 = 2.82 ÷ 2 = 1.41

5.6 ÷ 5 = 11.2 ÷ 10 = 1.12

Does that all make sense?

Let's have a go at some questions now.
