To know how to figure out percentages, we must first learn about the definition of percentages. This math help will definitely improve your understanding and get you ready to solve your own math problems. You probably have known that percentage uses % symbol, such as 35%, 70%, and 99.9%. Percentage is a way to compare a partial amount of something to its whole amount. In short, you might read % as “out of 100”.

In mathematics, percentage means partial divided by whole.
Example:
There are 10 apples in the basket, but 3 of them are rotten. What’s the percentage of fresh apples are in the basket?
Solution:
The partial amount → fresh apples: 10 – 3 = 7 apples.
The whole amount → total apples in the basket: 10 apples.
% = 7/10 = 0.7
So, 0.7% of the total apples are fresh.
Often, there are other variations of problems which require you to use these formulas:

In real life, we’ll often see the application of percentages starting from your allowance increase, interest rate, and discount! To calculate a discount, you have to know first how to figure out percentages.

If the shirt price is $50, then how much should you pay for the shirt? The discount is 30% x $50 = 30/100 x $50 = 3/10 x $50 = $15. Therefore, you need to pay $35. Or you can just calculate 70% x $50 = $15. It’s as simple as that when you have mastered how to figure out percentages!
