Question

In a classroom of 28 there are 12 boys and 16 girls. What fraction of the class are boys?

Answer 1

3/7 of the class are boys

Explanation:

we have :

a+b=c

a= girls =16

b=boys = 12

c= total= 28

a/c=16/28=4/7

b/c=12/28=3/7

so we have:

(3/7) * c= 12

(3/7) * 28=12

3/7 of the class are boys
