# 10 Things Most People Don't Know About calculate percentages If you have actually ever discovered yourself looking at a half-eaten pie, wondering how the part that's left compares to the size of the original pie, congratulations: You've been pondering percentages. Although technically the term "portion" refers to 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, one-half amounts to 50 percent, or 50 out of 100. You can use a calculator to quickly work out portions.
The three terms in a percentage estimation 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 math world, exercising portions normally means that one of those terms is missing out on and you need to find it. If the concern is "What percentage of 40 is 10?" you have the part (10) and the whole (40 ), so the left out term is the portion. 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. Utilizing the same logic, if the concern is "10 is 25 percent of what?" the the term is the entire.

If the omitted term is the percentage, divide the part by the whole utilizing your calculator to figure out the answer. For the example equation, this is 10 ÷ 40 = 0.25. If your calculator has a percentage button, press it to figure out the portion. If your calculator does not have such a button, multiply your previous answer by 100 to identify the portion: 0.25 x 100 = 25%.
