For every girl taking classes at the martial arts school, there are 3 boys who are taking classes at the school. If there are 236 students taking classes, write and solve a porportion to predict the number of boys taking the classes at the school.
So #girls:#boys = 1:3 or
#girls:(#girls + #boys) = 1:4 = #girls:236
This means #girls = (1/4)*236 = 59
So how many boys are there?
there are 177. you have to multiply 59 by 3
