What is a Percent?
A percent is a way to express a value as a fraction of 100. In other words, it is a ratio of a part to a whole, where the whole is equal to 100. Percentages are often used to represent a proportion or a fraction of a larger quantity.

The Formula for Finding Percent of a Number
The formula for finding the percent of a number is: (part/whole) x 100 = percentage. This formula can be used to calculate the percentage of a number by dividing the part by the whole and multiplying the result by 100. For example, if you want to find 25% of 100, you would use the formula: (25/100) x 100 = 25.
