In a survey of teenagers, 2/3 responded that they got regular exercise, and 4/5 of those said that walking was their main form of exercise. What fraction of the teenagers mainly exercise by walking?(

Answer 1

To find the fraction of teenagers who mainly exercise by walking, we can multiply the fractions together:

2/3 * 4/5 = (2 * 4)/(3 * 5) = 8/15.

Therefore, 8/15 of the teenagers mainly exercise by walking.
