One barnyard owl makes 5 hoot sounds per minute. If 5 less than 20 hoots per minute are heard coming out of the barn, how many Barnyard owls would this noise be coming from? Let's be accurate as possible.
5 less than 20 hoots per minute is 20 - 5 = 15 hoots per minute. If one barnyard owl makes 5 hoot sounds per minute, then 15 hoots per minute are coming from 15 / 5 = 3 barnyard owls.
The answer: 3.
