Hi!


Please help to solve the question:

The ratio of the number of males to the number of females at a performance is 5:7. 1/4 of the males and 3/4 of the females are children. What is the ratio of the number of adults to children? Express your answer in simplest form.

Thanks

males: females=5:7 =>20:28
¼= 20 , ¾=60
Children = 60-28=32
Ratio of the no of adults to children = 48:32= 3:2
