Caroline, Colin & Sarah share some money. Caroline gets 1/9 of the money.
Colin and Sarah share the rest in the ratio 1:3.
What proportion does Sarah get?

it is easy make me as brainliest

2 ÷ 3

Step-by-step explanation:

Let us suppose the money be 90

Since caroline gets 1 by 9 of the money i.e. 10

And, the remaining money would be distributed among Colin and sarah in the ratio of 1:3

So, the remaining money would be

= 90 - 10

= 80

So, the sarah could get

= 80 × 3 ÷ 4 ÷ 90

= 60 ÷ 90

= 20 ÷ 30

= 2 ÷ 3
