What is the percent

Percent is a way of expressing a number as a fraction of 100. It is denoted by the symbol %, which is placed after the number. For example, 50% means 50 out of 100, or 0.5.

Percentages are often used to express rates, proportions, and probabilities. For example, we might say that the unemployment rate is 5%, or that the chance of rain is 30%.

Percentages can also be used to compare two numbers. For example, we might say that the new product is 20% cheaper than the old product.

To calculate a percentage, we divide the number we are interested in by the total number, and then multiply the result by 100. For example, to find the percentage of people who voted for a particular candidate, we would divide the number of votes for that candidate by the total number of votes cast, and then multiply the result by 100.

Percentages are a useful way to express numbers because they allow us to make easy comparisons between different numbers. They are also widely used in many different fields, such as mathematics, science, economics, and finance.
