Question

5. A total of 64 athletes enter a competition, and of the athletes

are gymnasts. Some of the gymnasts perform a vault, and the rest
perform a floor routine. The ratio of the number of gymnasts
performing a vault to the total number of gymnasts in the
competition is 1 : 4. How many gymnasts perform a floor routine
in the competition? Explain.

• 18 gymnasts

Number of gymnasts, 3/8 of all athletes:

• 64*3/8 = 24

Number of gymnasts performing a vault, 1/4 of all gymnasts:

• 24*1/4 = 6

Number of gymnasts performing a floor routine, the rest of the gymnasts:

• 24 - 6 = 18
