Percent is a term used to describe a ratio that is part of the number 100, and is called a "%," also known as a percentage or percent symbol. The following examples illustrate this example:
Example 1: 4/5 ratio is equal to 80/100. Therefore, 4/5 means equal to 80%. This means that 4 is 80% of 5.
For example, a number like 2: 2 can be thought of as a 2/1 ratio equal to 200/100. Therefore, it is 200%.
