The diagram compares the ratio of girls in the chorus to boys in the chorus. (The diagram shows 3 boxes for the girls and 2 boxes for the boys.) If there are 50 students in the chorus, how many are girls and how many are boys?

ratio of girls to boys is 3:2....added = 5.....this means that 3/5 of the total students are girls and 2/5 of the total students are boys.

so if there are 50 students...
3/5(50) = 150/5 = 30 girls
2/5(50) = 100/5 = 20 boys
