Answer 1

To calculate the fraction of teenagers who mainly exercise by playing soccer, we need to multiply the fractions of teenagers who get regular exercise and play soccer as their main form of exercise.

Fraction of teenagers who get regular exercise = 3/4
Fraction of teenagers who play soccer as their main form of exercise = 5/9

Fraction of teenagers who mainly exercise by playing soccer = (3/4) * (5/9) = 15/36

Simplifying the fraction, we get:
15/36 = 5/12

Therefore, the fraction of teenagers who mainly exercise by playing soccer is 5/12.
