If you've ever found yourself gazing at a half-eaten pie, questioning 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-- say, that half-eaten pie-- compares to the entire. For example, half is equal to half, 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 percentage. In the equation: 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 one of those terms is missing and you need to discover it. If the question is "What portion of 40 is 10?" you have the part (10) and the entire (40 ), so the omitted term is the portion. If the question is "What is 25 percent of 40?" you have the percentage (25) and the whole (40 ), so the missing term is the part. Utilizing the very same logic, if the question is "10 is 25 percent of what?" the the term is the entire.
If the left out term is the percentage, divide the part by the whole using your calculator to determine the response. For the example equation, this is 10 ÷ 40 = 0.25. If your calculator has a portion button, press it to determine 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 increase the entire by the percentage to identify the response. 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 need to first divide the percentage by 100: 25 ÷ 100 = 0.25. You can then multiply this answer by the whole to identify 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 a portion button, the estimation is as follows: 10 ÷ 25% = 40. If your calculator does not have a portion button, you need to divide the portion by 100 prior to completing the computation: 25 ÷ 100 = 0.25. You can then divide the part by this response to figure out the whole: 10 ÷ 0.25 = 40. Calculating percentages can be an easy task.
