Question

A copy machine makes 36 copies per minute. How many copies does it make in four minutes and 45 seconds?

Answer 1

Answer: The copy machine makes 171 copies in 4 minutes and 45 seconds.

Explanation:

Let's dissect the question. The copy machine makes 36 copies per minute.

36 per min.

To see how many copies it makes in 4 minutes and 45 seconds, we multiply 36 * 4.75. 45 seconds is 3/4ths of a minute, or 0.75 of a minute.

`36 * 4.75=171`

It makes 171 copies in 4 minutes and 45 seconds.
