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 original pie, congratulations: You've been contemplating percentages. Although technically the term "portion" refers to a portion out of 100, in real-world terms it actually deals with how a portion 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 use a calculator to quickly work out portions.
The three terms in a portion computation are the part, the whole, and the portion. In the equation: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the portion. In the math world, working out percentages usually means that one of those terms is missing and you require to discover it. If the question is "What portion of 40 is 10?" you have the part (10) and the whole (40 ), so the left out term is the portion. If the question 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 same logic, if the concern is "10 is 25 percent of what?" the the term is the entire.
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 percentage button, press it to identify the portion. If your calculator does not have such a button, increase your previous answer by 100 to determine the percentage: 0.25 x 100 = 25%.

If the left out term is the part, utilize the calculator to multiply the whole by the percentage to identify 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 portion button, you need to initially divide the portion by 100: 25 ÷ 100 = 0.25. You can then increase this response by the entire 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 need to divide the percentage by 100 prior to completing the computation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to determine the whole: 10 ÷ 0.25 = 40. Computing percentages can be a simple job.
