Question

Caroline, Colin & Sarah share some money.

Answer 1

Caroline, Colin & Sarah share some money.Caroline will get $\dfrac{2}{3}$  when Caroline, Colin & Sarah share some money.

What is the ratio?

The ratio defined as the sharing of the two or three things or it represent that one thing or number is how many times to the other.

One part is excluded in the problem. That part is:

"Caroline gets $\dfrac{1}{9}$ of the money."

If Caroline gets 1/9th, then remaining is:

$1-\dfrac{1}{9}=\dfrac{8}{9}$

Colin and Sarah share in ratio 3 is to 1, that means 3 + 1 = 4 parts...

8/9th in 4 parts means, each part is:

$\dfrac{\dfrac{8}{9}}{4}=\dfrac{2}{9}$

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

$3\times \dfrac{2}{9}=\dfrac{6}{9}=\dfrac{2}{3}$

Colin gets  $\dfrac{2}{3}$ money when three of them share money.
