Question

Every 2/3 hour, Harris can sew 1/6 pair of jeans. What is Harris's rate in pairs of jeans per hour?

Answer 1

Whole hour - 2/3 = 1/3

1/3 + 1/6 = 2/6 + 1/6
= 3/6

Harris can sew half of a pair of jeans per hour.

Answer 2

1/4 per hour.
In 1/3 of an hour, he can sew 1/12 of jeans. Multiply that by three, which equals 1/4 or .25
