Answer 2

Hey!

The number of parts read is directly proportional to the hours read.

1 hours ≙ 1/3 part (≙ is symbol of correspondence.)

21/5 x 1 hours ≙ 21/5 x 1/3 part (multiply both sides of equal correspondence by 21/5)

21/5 x 1/3 = 7/5 = 14/10 = 1.4 parts

Hope that helps. If yes, please mark this as the answer you were looking for!
