Question

In a group of 36 children, there are twice as many boys as girls. How many girls are there?

Answer 1

12 girls

Explanation:

boys : girls

2x : x

There are twice as many boys as girls

The total is 36

2x+x = 36

3x= 36

Divide each side by 3

3x/3 = 36/3

x = 12

boys : girls

2*12 : 12

24 : 12

There are 24 boys and 12 girls
