Question

During a bake sale, 5 ¾ dozen cookies were sold in ⅓ hour. What is the unit rate for the dozens of cookies sold per hour?

Answer 1

The unit rate for the dozens of cookies sold per hour is 4.5 dozens per hour.

Explanation:

1.5 / 1/3 = 15 x 3 / 10 = 45/10 = 4.5

Answer 2

`17(1)/(4)`

Explanation:

Let's create a dozen to hour ratio

5 ¾ dozen cookies : ⅓ hour

Find the unit rate sold per HOUR, 1 divided by 1/3 is 3. So, we need to multiply both sides of the ratio by 3.

5 ¾ * 3 = 69/4 = 17 1/4

1/3 * 3 = 1

The answer is 17 1/4 dozen cookies per hour

Hope this helps :)

Have a nice day!
