# How to Master calculate percentages in 6 Simple Steps

If you have actually ever found yourself gazing at a half-eaten pie, wondering how the part that's left compares to the size of the original pie, congratulations: You've been considering portions. Although technically the term "percentage" describes a portion out of 100, in real-world terms it actually deals with how a part of something-- say, that half-eaten pie-- compares to the entire. For example, half amounts to half, or 50 out of 100. You can use a calculator to quickly work out percentages.

The three terms in a portion estimation are the part, the whole, and the percentage. In the formula: 25% of 40 = 10, 10 is the part, 40 is the whole, and 25 is the portion. In the math world, working out percentages typically indicates that one of those terms is missing out on and you need to find it. If the concern is "What percentage of 40 is 10?" you have the part (10) and the entire (40 ), so the omitted term is the portion. If the concern is "What is 25 percent of 40?" you have the percentage (25) and the entire (40 ), so the missing term is the part. Utilizing the exact same reasoning, if the question is "10 is 25 percent of what?" the the term is the whole.

If the left out term is the percentage, divide the part by the whole using your calculator to figure out the answer. For the example equation, this is 10 ÷ 40 = 0.25. If your calculator has a portion button, press it to figure out the percentage. If your calculator does not have such a button, increase your previous response by 100 to figure out the percentage: 0.25 x 100 = 25%.

If the omitted term is the part, use the calculator to multiply the entire by the portion to figure out the response. If your calculator has a percentage button, the calculation is as follows: 40 x 25% = 10. If your calculator does not have a percentage button, you should initially divide the portion by 100: 25 ÷ 100 = 0.25. You can then increase this response by the entire to figure out the part: 0.25 x 40 = 10.

If the left out term is the entire, divide the part by the portion to figure out the response. If your calculate percentages calculator has a portion button, the estimation is as follows: 10 ÷ 25% = 40. If your calculator does not have a portion button, you should divide the portion by 100 prior to finishing the estimation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to identify the whole: 10 ÷ 0.25 = 40. Calculating portions can be a simple job. There are many portion calculators online that can assist with task by just searching for "percentage calculator."
