Percentages are everywhere, and they are used to calculate a wide range of things. From discounts to taxes, percentages are used to make calculations quick and easy. Let’s look at some of the most common applications of percentages in the real world.

Discounts:

Discounts are a great way to save money, and they are often expressed in terms of a percentage. For example, if a store is offering a 20% discount on a product, that means you can buy it for 20% less than the original price. Understanding how percentages work can help you save money when shopping, as you can quickly calculate how much a product will cost after the discount has been applied.

Interest is often expressed as a percentage, and this is used to calculate the amount of money you will be charged for borrowing money.

Understanding how interest is calculated can help you make sure you are not paying too much for borrowing money.

In school, grades are often expressed as a percentage. For example, if you get a 90% on an exam, this means you have achieved 90% of the possible marks. Understanding how percentages work can help you understand how your grades are calculated and how to improve them.
