Fractions

We've been finding tenths of various amounts this week:

E.g. 3/10 of 40

6/10 of 20 

The children should know this is exactly the same as dividing...

1/10 of 30 is the same as 30 \ 10

When working out 3/10 of 40, the children must work out 1/10 first. Then multiply by the top number.

1/10 of 40 = 4

4 X 3 = 12

So 3/10 of 40 = 12
