# 10 Things You Learned in Kindergarden That'll Help You With calculate percentages If you have actually ever discovered yourself gazing at a half-eaten pie, wondering how the part that's left compares to the size of the original pie, congratulations: You have actually been considering 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 portion estimation are the part, the whole, and the portion. In the equation: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the portion. In the math world, exercising percentages normally means that a person of those terms is missing out on and you need to discover 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 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 exact same reasoning, if the question is "10 is 25 percent of what?" the the term is the whole.

If the left out term is the portion, divide the part by the whole utilizing your calculator to determine the answer. For the example formula, this is 10 ÷ 40 = 0.25. If your calculator has a portion button, press it to determine the percentage. 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 omitted term is the part, use the calculator to multiply the entire by the portion to figure out the response. If your calculator has a percentage button, the calculation is as follows: 40 x 25% = 10. If your calculator does not have a percentage button, you should initially divide the portion 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 percentage 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 before completing the calculation: 25 ÷ 100 = 0.25. You can then divide the part by this answer to determine the whole: 10 ÷ 0.25 = 40. Calculating percentages can be a simple job.
