#### How to calculate percentages

If you need to calculate a percentage, there are a few different ways to do it. You can use a calculator, or do the math by hand.

To calculate a percentage on a calculator, you will first need to convert the percentage into a decimal. To do this, simply move the decimal point two places to the left. For example, if you have 10%, you will convert it to 0.10.

Once you have the decimal, simply multiply it by the number you are trying to find the percentage of. So, if you want to find 10% of 100, you would multiply 0.1 by 100 to get 10.

You can also calculate percentages by doing the math by hand. To do this, you will need to use basic multiplication and division.

First, take the percentage and divide it by 100. So, if you have 10%, you would divide it by 100 to get 0.1.

Next, take the number you are trying to find the percentage of and multiply it by the answer from the previous step. So, if you want to find 10% of 100, you would multiply 100 by 0.1 to get 10

There are a number of different ways to calculate percentages, and a Percentage Calculator can help you find the method that best suits your needs.

#### b. without a calculator

It's easy to find a percentage calculator online, but what if you don't have a calculator handy? Here are a few methods you can use to calculate percentages without a calculator.

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.
