Question

The Baldwin family walked 4/5 of a mile in 4/9 of an hour. What is their unit rate in miles per hour?

Answer 1

1.8mph

Explanation:

you must multiply both fractions by the reciprocal of 4/9 which is 9/4

(4/5 * 9/4) / (4/9 * 9/4)

(36/20) / (36/36)

9/5 or 1.8 / 1/1 or 1

1.8/1 = 1.8 mph
