# A copy machine makes 44 copies per minute. How long does it take to make 187 copies?

## Question:

A copy machine makes 44 copies per minute. How long does it take to make 187 copies?

## Ratios and Proportions:

Ratios and proportions can be used to solve certain scenarios. A set ratio needs to be established and then one can find out a missing variable for another ratio by using proportions.

In this scenario, it is established that a copy machine makes 44 copies in one minute. So in order to find out how long it takes to make 187 copies, a proportion is set up.

44 copies / 1 min = 187 copies / x min

So one multiplies 187 by 1 and then divides by 44 to solve for x.

X then equals 4.25 minutes.
