Caroline, Colin & Sarah share some money.
Caroline gets of the money.
Colin and Sarah share the rest in the ratio 3:1.
"What proportion does Colin get?

Colin gets  

Step-by-step explanation:

We know Colin gets "3" parts of the total, each part is (2/9)th, so 3 parts would be:

Colin gets  

2/3x + 7 = 29
