To **calculate a percentage** of a number, simply divide the number by 100. For example, *25% of 80 is equal to 80 divided by 100, or 0.80*.

To **calculate a percentage** of multiple numbers, add the numbers together first, then divide by 100. For example, *30% of 40 and 50% of 60 is equal to (40 + 60) divided by 100, or 1.00*.

If you're trying to find what percentage one number is of another, you can use the following formula: *percent = (number ÷ total) × 100*. So, if you wanted to know what percent 60 is of 200, you would divide 60 by 200 to get 0.30, then multiply by 100 to get 30%.

#### What are some common percentage calculations?

One of the most common percentage calculations is finding what percent one number is of another number. For example,* if you wanted to know what percent 4 is of 20, you would divide 4 by 20 to get 0.2*. You would then multiply that answer by 100 to get 20%. To **calculate the percentage** of a change, you would take the difference between the two numbers and divide it by the original number. For example,* if someone's height increased from 5 feet to 6 feet, that would be a 20% increase*. To find the percent decrease, you would take the difference between the two numbers *(6-5 = 1)* and divide it by the original number *(5*). This would give you a* 20%* decrease.
