If you've ever discovered yourself staring at a half-eaten pie, wondering how the part that's left compares to the size of the original pie, congratulations: You've been contemplating percentages. Although technically the term "percentage" describes a part out of 100, in real-world terms it really handles how a portion of something-- state, that half-eaten pie-- compares to the entire. For instance, half amounts to 50 percent, or 50 out of 100. You can use a calculator to quickly exercise percentages.
The 3 terms in a percentage estimation are the part, the entire, and the percentage. In the formula: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the portion. In the math world, working out portions generally suggests that a person of those terms is missing out on 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 left out term is the percentage. If the concern is "What is 25 percent of 40?" you have the percentage (25) and the entire (40 ), so the missing term is the part. Using the same reasoning, 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 identify 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 figure out the portion: 0.25 x 100 = 25%.

If the left out term is the part, use the calculator to multiply the entire by the portion to determine the answer. 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 percentage by 100: 25 ÷ 100 = 0.25. You can then multiply this answer by the whole to figure out the part: 0.25 x 40 = 10.
If the omitted term is the entire, divide the part by the portion to figure out 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 should divide the percentage by 100 before completing the computation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to determine the whole: 10 ÷ 0.25 = 40. Determining portions can be a simple job.
