Question

There are 45 students in a class. The ratio of boys to girls is 2:3. How many boys are there in the class?

Answer 1

18 boys

Explanation:

we add 2 and 3 because they are equal parts:

2+3=5

Then we divide 45 by 5 because we want to find what 1 part equals"

45/5=9

We now do 9*2 to get an answer of:

9*2=18

hope this makes sense!
