The ratio of boys to girls in Mrs. Harrison's math classes is 5:7. If there are 120 students in an
of her classes, how many are boys.​

Answer 1

50 Boys

70 Girls

Explanation:

Lets take the no. of boys = 5x

and girls = 7x

Total no. of students in ratio = 12x

Total no of students = 120

Therefore, 12x = 120

x = 10

So, no. of boys = 5x = 5*10 = 50

No. of girls = 7x = 7*10 = 70
