In the senses “rate or proportion per hundred” and “proportion in general” percent and percentage are frequently interchangeable. With a preceding number, only percent occurs ( a 16 percent decline ); with no preceding number, either occurs, but percentage is much more common: a certain percentage (or percent ) of the land.

Etymology

Origin of percent

First recorded in 1560–70; short for Medieval Latin per centum “by the hundred”; see per, cent

Explanation

A percent is part of something, split into a hundred pieces. For example, fifty percent of forty is twenty. You'll hear a lot about percent and percentages in math. A percent can go from 0 percent to 100 percent. A percent is calculated by comparing a part of something compared to the whole. A baseball player's batting average is a percent. Athletes are known for talking about numbers that are impossible, like "I gave 110 percent!" You can do that in slang, but don't try it in math class.
