Answer:
1/4
Step-by-step explanation:
To calculate a unit ratio, we need to get the fractions to whole numbers.
Since we want the unit rate based on hours, we must multiply both sides by the number that, when multiplied by 2/3 = 1.
Multiply each term by 1 1/2 since 2/3 x 1 1/2 = 1
2/3 x 1 1/2 = 1 hour
1/6 x 1 1/2 = 1/4 pairs of jeans
1/4 pairs of jeans per hour
