Question

This year Deandre watched 20 movies. He thought that 14 of them were very good. Of the movies he watched, what percentage did he rate as very good?

Answer 1

70%

Explanation:

We can model percentage problems using the ratios:

is / of = % / 100.

We're essentially asking 14 "is" what percent "of" 20? Thus, 14 is the "is" value and 20 is the "of" value. Plugging these in will allow us to find the percentage:

14 / 20 = % / 100

7/10 = % / 100

70 = %

Thus, of the movies Deandre watched, he rated 70% of them as very good.
