I’m a survey of teenagers 2/3 responded that they got regular exercise and 4/5 of those said that walking was main from of exercise what fraction of the teenagers mainly exercise by walking
To find the fraction of teenagers who mainly exercise by walking, we need to multiply the fractions of teenagers who got regular exercise (2/3) and those who said walking was their main form of exercise (4/5).
Fraction = (2/3) * (4/5)
= 8/15
Therefore, 8/15 of the teenagers mainly exercise by walking.
