# How to Master calculate percentages in 6 Simple Steps If you've ever found yourself staring at a half-eaten pie, questioning how the portion that's left compares to the size of the initial pie, congratulations: You've been contemplating portions. Although technically the term "percentage" describes a portion out of 100, in real-world terms it truly deals with how a part of something-- say, that half-eaten pie-- compares to the whole. For instance, one-half is equivalent to 50 percent, or 50 out of 100. You can utilize a calculator to easily exercise percentages.
The 3 terms in a portion computation are the part, the entire, and the percentage. In the formula: 25% of 40 = 10, 10 is the part, 40 is the whole, and 25 is the percentage. In the mathematics world, working out percentages usually implies that a person of those terms is missing and you need to discover it. If the question is "What percentage of 40 is 10?" you have the part (10) and the entire (40 ), so the left out term is the percentage. If the concern is "What is 25 percent of 40?" you have the portion (25) and the whole (40 ), so the missing term is the part. Using the very 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 portion, divide the part by the whole using your calculator to determine the response. For the example formula, this is 10 ÷ 40 = 0.25. If your calculator has a portion button, press it to determine the percentage. If your calculator does not have such a button, increase your previous response by 100 to determine the percentage: 0.25 x 100 = 25%.

If the omitted term is the part, use the calculator to increase the entire by the portion to figure out the answer. 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 calculator has a portion button, the calculation is as follows: 10 ÷ 25% = 40. If your calculator does not have a percentage button, you must divide the percentage by 100 prior to finishing the estimation: 25 ÷ 100 = 0.25. You can then divide the part by this response to figure out the entire: 10 ÷ 0.25 = 40. Computing portions can be a simple task.
