Question

Caroline, Colin & Sarah share some money in the ratio 1 : 9 : 1.
In total, Caroline and Sarah receive £28.
How much does Colin get?

Answer 1

Answer:

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 8/9....so....each 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
