If you've ever found yourself gazing 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" refers to a part 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 portions.
The 3 terms in a percentage 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 portion. In the math world, exercising percentages generally indicates 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 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 portion, divide the part by the whole utilizing your calculator to determine the answer. 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, multiply your previous response by 100 to figure out the portion: 0.25 x 100 = 25%.

If the omitted term is the part, use the calculator to multiply the whole by the portion to figure out the response. If your calculator has a portion button, the calculation is as follows: 40 x 25% = 10. If your calculator does not have a percentage button, you should first divide the percentage 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 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 entire: 10 ÷ 0.25 = 40. Computing portions can be a simple job.
