The ratio of team leaders to players is 1:18. How many team leaders will be

needed for 72 players?

4

Step-by-step explanation:

if the ratio is 1:18 that means for every 18 players there will be 1 team leader. A simple way to find the answer to problems involving ratios is to simply plug in the numbers. In this case the ratio is 1:18, so first plug in the number you have by dividing the amount of players by the original ratio given, so 72/1 = 1. This makes 72:18, then divide 72/18 = 4.
