Question

7. Sonia's class has 24 girls and 8 boys. Her school has a total
enrollment of 860 students. If the school has the same ratio of
airls to boys as Sonia's class, how many girls are in the school?

Answer 1

Ratio of girls to total students: 24 / 32

Proportion: 24 / 32 = x / 860

Solving proportion for x:

32x = 20640

x = 645 girls

There are 645 girls in the school.

Hope this helps!! :)
