Ms Price has three times as many girls as boys in her classroom Ms Lippy has twice as many girls as boys. Ms. Price has 60 students, and Ms Lippy has 135 students. If the classes were combined into one, what would be the ratio of girls to boys?

x + 3x = 60 ; x boys ; x = 15

x + 2x = 135; x boys; x = 45

so combined total 60 boys & (45+90)girls

ratio is 135 : 60
