Question

Two brothers, richard and andrew share a sum £30 in the ratio 3:7 how much does each brother get?

Answer 1

Richard gets: £9

Andrew gets: £21

Explanation:

To get the value of 1 part we have to add the total number of parts (3+7) and then divide them by the sum (30) 30/10 = 3 so we know 1 part is £3

Thus Richard gets: £3*3 = £9

And Andrew gets: £3*7 = £21

Answer 2

7+3 = 10
30/10 = 3
3(3) = 9
7(3) = 21

richard gets 9
andrew gets 21
