# 9 Signs You're a percent calculator Expert

If you've ever found yourself staring at a half-eaten pie, wondering how the part that's left compares to the size of the initial pie, congratulations: You've been pondering percentages. Although technically the term "portion" describes a part out of 100, in real-world terms it truly handles how a portion of something-- say, that half-eaten pie-- compares to the whole. For instance, half amounts to 50 percent, or 50 out of 100. You can use a calculator to easily work out percentages.
The three terms in a percentage estimation are the part, the whole, and the percentage. In the equation: 25% of 40 = 10, 10 is the part, 40 is the entire, and 25 is the portion. In the mathematics world, working out percentages normally implies that one of those terms is missing and you need to find it. If the concern is "What portion 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 percentage (25) and the whole (40 ), so the missing term is the part. Using the exact same logic, if the concern is "10 is 25 percent of what?" the the term is the whole.

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

If the left out term is the part, use the calculator to multiply the whole by the percentage to determine 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 portion by 100: 25 ÷ 100 = 0.25. You can then multiply this answer 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 percentage to identify the answer. If your calculator has a portion button, the computation is as follows: 10 ÷ 25% = 40. If your calculator does not have a portion button, you should divide the portion by 100 before finishing the calculation: 25 ÷ 100 = 0.25. You can then divide the part by this response to figure out the whole: 10 ÷ 0.25 = 40. Determining portions can be an easy job. There are various portion calculators online that can assist with task by simply browsing for "percentage calculator."
