Hi!
So I would do this problem by dividing 165 copies by 3 minutes and 45 seconds; that's finding how many 3 minutes and 45 seconds go into 165, and results in how many copies are made in a minute.
Since 3 minutes and 45 seconds is in reality, 3 3/4 minutes, as there are 60 seconds in a minute, I would divide by 3 3/4, or 3.75.
165 / 3.75 = 44
So therefore, a copy machine makes 44 copies per minute.
