# 10 Compelling Reasons Why You Need percentage calculator If you've ever found yourself looking at a half-eaten pie, questioning how the portion that's left compares to the size of the initial pie, congratulations: You've been pondering percentages. Although technically the term "portion" refers to a part out of 100, in real-world terms it truly handles how a portion of something-- state, that half-eaten pie-- compares to the whole. For instance, one-half amounts to 50 percent, or 50 out of 100. You can utilize a calculator to easily exercise portions.
The three terms in a portion calculation are the part, the entire, and the percentage. In the equation: 25% of 40 = 10, 10 is the part, 40 is the whole, and 25 is the portion. In the mathematics world, working out portions generally means that a person of those terms is missing and you require to discover it. If the question 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 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 identify the response. For the example formula, this is 10 ÷ 40 = 0.25. If your calculator has a percentage 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 computation is as follows: 40 x 25% = 10. If your calculator does not have a portion 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 omitted term is the whole, divide the calculate percentages part by the percentage to determine the answer. If your calculator has a percentage 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 completing the calculation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to determine the whole: 10 ÷ 0.25 = 40. Calculating portions can be a simple job.
