The average number of swimmers per lifeguard, where there are 120 swimmers and 6 lifeguards, is 20.
The average or mean is the quotient of the total value divided by a stated number.
We can also express the resulting quotient as a percentage of the total value.
The total number of swimmers = 120
The total number of lifeguards available = 6
The average number of swimmers per lifeguard = 20 (120 ÷ 6)
Percentage of lifeguards to swimmers = 5% (6/120 x 100)
Thus, for each lifeguard, there are 20 swimmers. In other words, we can conclude that the percentage of lifeguards to swimmers is 5%.
