Answer 1

15 and 21

Explanation:

Explanation:

Let the ratio of boys and girls be 5x and 7x

According to question-

no. of boys +no. of girls =total students

5x + 7x = 36

12x = 36

x = 36/12

x = 3

Therefore,

No. Of boys = 5x =5 * 3 =15

No. Of girls = 7x = 7 * 3 = 21

Answer 2

There are 6 more girls than boys in a class of 36 with a boy ratio of 5:7

Explanation:

5:7 where 5 + 7 = 12

therefore 12 x 3 = 36

3 x 5 = 15 boys

3 x 7 = 21 girls

21-15 = 6 more girls.
