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.
