To find the fraction of teenagers who mainly exercise by walking, we need to multiply the fractions representing the proportions of teenagers who got regular exercise and whose main form of exercise is walking.
The fraction of teenagers who got regular exercise is ⅔.
⅘ of those teenagers said that walking was their main form of exercise.
To find ⅘ of ⅔, we multiply these fractions.
⅘ * ⅔ = (8/10) * (2/3) = 16/30
Simplifying the fraction, we get:
16/30 = 8/15
So, 8/15 of the teenagers mainly exercise by walking. Therefore, the answer is 8/15.
In a survey of teenagers, ⅔ responded that they got regular exercise, and ⅘ of those said that walking was their main form of exercise. What fraction of the teenagers mainly exercise by walking? (1 point)
