Question

Action movies make up 85% of Devon's movie collection. If he has 20 movies, how many action movies are in Devon's collection?

Answer 1

`17`

Explanation:

`85% = 85/100`

`85%` of `20 = 0.85 * 20`

`0.85 * 20 = (0.85 * 100)/5`

`= 85/5`

`= 17`

to check:

`17/20 = (17*5)/100 = 85/100`

`85/100 = 85%`
