Question

In a soccer team, 1/3 of the players ride a bike to practice, 25% walk to practice and the remaining 15 players are driven by their parents. How many players are there in the team?

a. 42 b. 36 c. 30 d. 21

Answer 1

25% = 1/4
Find what fraction of the players are not from the 15
1/3 + 1/4 = 7/12
Find what fraction of them are in the 15
1-7/12=5/12
Find original number
15/(5/12)=36
There are 36 players on the team
