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

Richard gets: £9

Andrew gets: £21

Step-by-step 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
