A prize of £3.60 is to be shared between 3 boys, so that for every 15p Jim has, Jack will have 30p,and Tom's share is always 3 times as much as Jim's.
How much will each boy receive?
Jim's share --- 15x
Jack's share --- 30x
Tom's share ---- 3(15x) = 45x
15x+30x+45x = 360
90x = 360
x = ....
find x, sub back into my definitions
