If you've ever discovered yourself looking at a half-eaten pie, questioning how the portion that's left compares to the size of the original pie, congratulations: You've been pondering 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 example, half amounts to half, or 50 out of 100. You can utilize a calculator to quickly exercise percentages.
The 3 terms in a percentage calculation are the part, the whole, and the percentage. In the equation: 25% of 40 = 10, 10 is the part, 40 is the whole, and 25 is the portion. In the math world, working out portions typically suggests that a person of those terms is missing and you require 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 exact 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 equation, this is 10 ÷ 40 = 0.25. If your calculator has a portion button, press it to figure out the portion. If your calculator does not have such a button, increase your previous response by 100 to determine the percentage: 0.25 x 100 = 25%.

If the left out term is the part, use the calculator to increase the entire by the percentage 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 percentage button, you must first divide the percentage by 100: 25 ÷ 100 = 0.25. You can then increase this response by the entire to figure out the part: 0.25 x 40 = 10.
If the omitted term is the whole, divide the part by the portion to identify the response. If your calculator has a portion button, the calculation 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 finishing the computation: 25 ÷ 100 = 0.25. You can then divide the part by this response to figure out the entire: 10 ÷ 0.25 = 40. Determining percentages can be an easy task.
