Question

At Carly's Pancake House there are 39 dirty coffee mugs and 21 clean coffee mugs. What

percentage of the coffee mugs at the pancake house are dirty?

Answer 1

65%

Explanation:

What you need to do is add both the clean and the dirty mugs together to get a total amount of mugs (60) and then divide 39 by 60 because you are dividing the mugs that you want to find the percentage of by the total amount of mugs. The equation would look like this:

39/60=0.65

therefore, the answer is 65%
