Usage
What is a percentage? Percentage is a rate or proportion per hundred, as in This graph shows the percentage of homes that have a microwave. Percentage is also used more generally to mean any proportion, as in Studies have shown that a large percentage of people love cute animals. A percent is one one-hundredth (1/100) of something. Percentage refers to the rate or proportion of that one hundred. Usually, you will see the word percentage used in math equations or statistics or when someone is measuring the increase and decrease in rates. Informally, percentage can mean a gain or advantage, as in There is no percentage to be gained from lying to the sheriff. Generally, percentage and percent can be used interchangeably when referring to vague proportions. However, the word percentage never follows an exact number. In this case, only percent can be used in The number of pet owners increased by 10 percent. A percentile is any of the possible 100 equal parts a range of values can be divided into. A given percentile means that the percentage of all possible outcomes is lower or lesser than the given percentile. For example, if you score in the 92nd percentile of an exam, you scored higher than 92 percent of all other people who took the exam. Example: After careful measuring, the percentage of people who hated pineapple on pizza was found to be significantly higher than first thought.

Etymology
Origin of percentage
Explanation
A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction. All of something is 100 percent, half of it is fifty percent, none of something is zero percent. To determine a percentage, you divide the portion of the whole by the whole itself and multiply by 100. So if you just ate two pieces of an eight-piece pie, and you want to know what percentage of the pie you consumed, you'd first divide 2 by 8 which equals .25. Then multiply .25 times 100 and get 25 percent. A percentage can also mean a portion of something but only when it has to do with numbers. When you buy furniture, the salesman gets a percentage of what you spend.
