Question 729488
Percent of desired things times total number of things is number of desired things.  Percent is number divided by 100.<P>
For the playground:  5/100 * 80 = 4 teachers.  The ratio of teachers to people is 4/80 = 1/20.<P>
For the gym:  15/100 * 60 = 9 teachers.  The ratio of teachers to people is 9/60 = 3/20.<P>
The gym has the higher ratio.
