A copy machine makes 44 copies per minute. How many copies does it make in 5 minutes and 45 seconds

Set up a proportion of copies to minutes where c is the number of copies for 5 minutes and 45 seconds.

Since 45 seconds is:
45/60 = 3/4 of a minute, we have:
5 minutes and 45 seconds = 5.75 minutes

44/1 = c/5.75

To solve this proportion, we type it in our search engine and we get:
c = 253
