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 "percentage" refers to a portion out of 100, in real-world terms it really handles how a portion of something-- say, that half-eaten pie-- compares to the entire. For instance, one-half amounts to 50 percent, or 50 out of 100. You can use a calculator to quickly work out percentages.
The 3 terms in a portion calculation are the part, the entire, and the portion. In the formula: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the portion. In the mathematics world, exercising portions generally suggests that a person of those terms is missing out on and you need to find 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 percentage. 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 same logic, if the concern 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 identify the portion: 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 response. 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 increase this response by the entire to identify the part: 0.25 x 40 = 10.
If the left out term is the entire, divide the part by the portion to determine 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 must divide the percentage by 100 prior to completing the estimation: 25 ÷ 100 = 0.25. You can then divide the part by this response to figure out the entire: 10 ÷ 0.25 = 40. Computing percentages can be an easy task.
