Please help me!I really need it

Answer 1

88

Explanation:

108 ÷ 3 = 36 = number of girls in the club.

108 + 36 = 144 = total number of people in the club.

(144 ÷ 9) x 2 = 32 = total number of runners in the club

32 x 3/8 = 12 = number of runners who are girls

32 - 12 = 20 = number of boys who are runners

108 - 20 = 88 = number of boys who are swimmers

Answer 2

88

Explanation:

Boys : Girls = 3 : 1

3x = 108

x = 36

Boys : Girls = 108 : 36

Total = 108 + 36 = 144

Swimmers : Runners = 7 : 2

7x + 2x = 9x

9x = 144

x = 16

Runners = 2 x 16 = 32

Girl Runners = 3/8 x 32 = 12

Boy Runners = 32 - 12 = 20

Boys Swimmer = 108 - 20 = 88
