Question

Every 2/3 hour, Harris can sew 1/6 pair of jeans.  What is Harris's rate in pairs of jeans per hour? Drag and drop the correct value into the box.
Options:
9, 4, 1/9, 1/4

Answer 1

Divide the number of pairs of jeans by the time.

(1/6)/(2/3) = 1/6 * 3/2 = 3/12 = 1/4

He can sew 1/4 pair of jeans per hour.

Answer 2

Write the rate as a fraction and then reduce it:

(1/6 pair of jeans)      1     3
------------------------ = --- * --- pairs of jeans per hour  = 1/4 pair per hour
   (2/3 hour)               6      2
