Answer:

8

Step-by-step explanation:

Firstly, we can simplify the ratio of boys to girls to

1:2.

Then, to find out how many students each ratio represents, we add up 1 and 2 and to get 3(1+2=3)

By dividing

3

by the number of students, we can find how many students ONE ratio represents:

24

---- = 8

3

So ONE ratio is equal to 8

boys. Since our simplified ratio of boys to girls is

1:2.

already, we do not have to do further multiplying - the number of boys is simply 8.

For the girls, simply multiply 2 by 8 to get 16.

Check:

8 boys + 18 girls = 24 students.
