If you have actually ever discovered yourself gazing at a half-eaten pie, wondering how the part that's left compares to the size of the original pie, congratulations: You have actually 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-- state, that half-eaten pie-- compares to the whole. For instance, one-half amounts to 50 percent, or 50 out of 100. You can use a calculator to quickly work out portions.
The three terms in a portion calculation are the part, the entire, and the portion. In the equation: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the percentage. In the math world, exercising percentages normally means that a person of those terms is missing out on and you need to discover it. If the concern is "What percentage of 40 is 10?" you have the part (10) and the whole (40 ), so the left out term is the percentage. If the question is "What is 25 percent of 40?" you have the portion (25) and the entire (40 ), so the missing term is the part. Using the exact same reasoning, if the concern is "10 is 25 percent of what?" the the term is the whole.
If the omitted 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 figure out 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 need to first divide the portion by 100: 25 ÷ 100 = 0.25. You can then increase this response by the whole to determine the part: 0.25 x 40 = 10.
If the omitted term is the whole, divide the part by the percentage to determine the answer. If your calculator has a percentage button, the computation is as follows: 10 ÷ 25% = 40. If your calculator does not have a percentage button, you should divide the percentage by 100 before completing the percent calculator computation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to identify the whole: 10 ÷ 0.25 = 40. Calculating percentages can be a simple job. There are many portion calculators online that can assist with job by just looking for "percentage calculator."
