# 11 Ways to Completely Ruin Your calculate percentages

If you've ever discovered yourself staring at a half-eaten pie, wondering how the portion that's left compares to the size of the initial pie, congratulations: You have actually been pondering percentages. Although technically the term "percentage" refers to a portion out of 100, in real-world terms it actually deals with how a portion of something-- say, that half-eaten pie-- compares to the whole. For example, one-half amounts to 50 percent, or 50 out of 100. You can utilize a calculator to easily exercise percentages.
The 3 terms in a percentage 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 mathematics world, working out portions typically suggests that one of those terms is missing out on 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 left out term is the percentage. If the concern is "What is 25 percent of 40?" you have the percentage (25) and the entire (40 ), so the missing term is the part. Utilizing the very same logic, 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 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, utilize the calculator to multiply the entire by the percentage to figure out the answer. If your calculator has a portion button, the calculation 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 whole to determine the part: 0.25 x 40 = 10.
If the omitted term is the whole, divide the part by the percentage to figure out the answer. If your calculator has a portion button, the calculation is as follows: 10 ÷ 25% = 40. If your calculator does not have a percentage button, you should divide the portion by 100 prior to finishing the estimation: 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 an easy job.
