Answer 1

25% of the 9th grade belongs to more than one club.

9th grade population 180

1 club                    =    90
2 clubs                  =    33
3 or more clubs    =    12 
Students w/ clubs    135

2 clubs + 3 or more clubs = 33 + 12 = 45 ÷ 180 = 0.25 x 100% = 25%
1 club = 90 ÷ 180 = 0.50 x 100% = 50%
no club = 180 - 135 = 45 ÷ 180 = 0.25 x 100% = 25%
