Answer:
75%
Explanation:
15 x 5 75
---- = -------
20 x 5 100
Cent means 100, so percent literally means per 100 like in century or centennial. So, I put it into a fraction over 100. Now it is 75 per 100. If you remember, per 100 is percent, it means the answer id 75 percent. You can also write it as 75%.
