A percent means a part of a hundred. People mark it with a percent sign after the number. It shows one value against a total in a simple way. Many areas use percent to measure and compare. You see it in prices, scores, and rates.

You start by dividing the part by the whole. You multiply the result by 100. For example, 20 divided by 80 gives 0.25. Multiplying by 100 turns it into 25 percent. This method fits discounts, growth, and shares.

People track percent to follow price drops and loan rates. Investors use it to measure profit. Teachers apply it to assign grades. Doctors check it to rate success. Mastering percent proves useful in many tasks.
