If you've ever discovered yourself staring at a half-eaten pie, wondering how the portion that's left compares to the size of the initial 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 whole. For instance, half amounts to half, or 50 out of 100. You can use a calculator to easily exercise percentages.
The three terms in a portion computation are the part, the whole, and the percentage. In the formula: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the percentage. In the mathematics world, working out percentages usually indicates that a person of those terms is missing and you need to find it. If the question is "What percentage of 40 is 10?" you have the part (10) and the whole (40 ), so the omitted 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 same reasoning, 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 identify 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, multiply your previous response by 100 to figure out the percentage: 0.25 x 100 = 25%.

If the left out term is the part, utilize the calculator to increase the entire by the portion to identify the answer. If your calculator has a portion button, the estimation is as follows: 40 x 25% = 10. If your calculator does not have a portion button, you must first divide the percentage by 100: 25 ÷ 100 = 0.25. You can then multiply this response 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 identify the answer. If your calculator has a percentage button, the calculation is as follows: 10 ÷ 25% = 40. If your calculator does not calculate percentages have a portion button, you need to divide the portion by 100 prior to finishing the computation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to figure out the whole: 10 ÷ 0.25 = 40. Calculating portions can be an easy job.
