What is Percentage?

An introduction

Percentage is a mathematical number expressed as a fraction with a denominator of 100. It is normally denoted with the percentage (%) symbol. For example, the fraction \(\frac{50}{100}\) could also be written as \(50\%\). That example is simple, because the denominator of our fraction is already 100. Another example is that the ratio \(\frac{20}{40}\) could also be written as \(50\%\). Note that both are equivalent fractions, but are written differently. Percentage allows us to normalize numbers and ratios that otherwise appear quite different. The concept of percentage is used by many people in day to day life. It can be used for many things such as calculating your score on a test or calculating how much tip to leave your waiter at a restaurant. It can help keep track of performance over time and it can help make sense of complex stock market prices. The concept of normalizing numbers of any size to a simple ratio with a base of 100 is one that has an unlimite number of uses.
