Question

The rules for World Cup Football call for a maximum of 3 goalies per team. This means that 13% of the team is comprised of goalies.
Which proportion can you solve to determine the total number of players, p, on the team?

Answer 1

Set up the proportion "3 is to p as 13 is to 100":
3/p = 13/100

Solve: p = 3·100/13 = 300/13 ≈ 23.08, so the roster is about 23 players (typically p = 23).
