Question 617525: 180 students are graduating from Johnson HS. If the ratio of the grils to boys is 5:4, how many boys are in the class
Answer by Maths68(1474) (Show Source): You can put this solution on YOUR website!
Ratio of the girls to boys = 5:4 = 5/4
5+4=9 means 4 out of 9 are boys
So
Boys = (4/9)(180)=4(20)=80
Girls = 180-80=100
Check
======
Girls/Boys = 100/80 = 10/8 = 5/4=5:4
