In a community fitness group, 40% of members run for exercise and 36% of members run and play a sport. What percentage of members who run for exercise also play a sport?
Imagine you have 100 people, this means 40 of them run for exercise. We also know 36 people run for exercise AND play a sport. So 36 of the 40 runners are the percentage we are looking for, this would be 36/40=0.9 or 90%
