Answer:

16 girls in the class

14 boys in the class

Step-by-step 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!
