# How to Explain calculate percentages to Your Boss If you have actually ever discovered yourself looking at a half-eaten pie, wondering how the portion that's left compares to the size of the initial pie, congratulations: You've been considering portions. Although technically the term "portion" describes a portion out of 100, in real-world terms it really handles how a part of something-- state, that half-eaten pie-- compares to the entire. For example, half amounts to 50 percent, or 50 out of 100. You can use a calculator to quickly exercise percentages.
The three terms in a portion estimation are the part, the whole, and the portion. In the formula: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the percentage. In the math world, working out percentages typically means that a person of those terms is missing and you require 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 percentage. 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. Using the very same logic, if the concern 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 identify the response. For the example formula, this is 10 ÷ 40 = 0.25. If your calculator has a percentage button, press it to identify the portion. 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 percentage calculator 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 before finishing the calculation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to identify the entire: 10 ÷ 0.25 = 40. Computing portions can be a simple job.
