Question

30 points!!!! a class of 30 students the Ratio of the numbers of boys to girls 7:8

How many girls are there in the class?
​

Answer 1

16 girls in the class

14 boys in the class

Explanation:

Because of the ratio of 7:8, I added 7+8.

7+8= 15

30 (the number of students in the class) divided by 15 (the sum of the ratio)

30/15= 2

I then multiplied 8 from the "girls" part of the ratio by 2 (the quotient of 30/15) and got 16. Then I subtracted 16 from 30 and got 14, which s the number of boys in the class.

Hope this helps!
