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?

Colin and Sarah get  1 - 1/9  = 8/9 of the money

A ratio   of 3 :1 means that there are 4 parts  of  the 8/9soeach part  =  8/9 * 1/4  = 8/36  = 2/9

And Colin gets 3 parts of  the  8/9  =  3 * 2/9  =  6/9   = 2/3 of the money
