# 10 Situations When You'll Need to Know About calculate percentages

If you have actually 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 have actually been contemplating portions. Although technically the term "percentage" refers to a part out of 100, in real-world terms it truly handles how a part of something-- say, that half-eaten pie-- compares to the entire. For instance, one-half is equal to half, or 50 out of 100. You can utilize a calculator to quickly exercise portions.

The 3 terms in a percentage calculation are the part, the whole, 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 mathematics world, exercising portions typically suggests that a person of those terms is missing and you need to discover it. If the question is "What percentage of 40 is 10?" you have the part (10) and the whole (40 ), so the omitted term is the portion. If the concern 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 very same reasoning, if the concern is "10 is 25 percent of what?" the the term is the entire.

If the omitted term is the portion, divide the part by the whole using your calculator to determine 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 percentage. If your calculator does not have such a button, increase your previous answer by 100 to determine the percentage: 0.25 x 100 = 25%.

If your calculator has a portion button, the calculation is as follows: 40 x 25% = 10. If your calculator does not have a portion button, you need to first divide the percentage by 100: 25 ÷ 100 = 0.25. You can then multiply this answer by the whole to figure out the part: 0.25 x 40 = 10.

If the left out term is the entire, divide the part by the portion to figure out the response. If your calculator has a percentage button, the estimation is as follows: 10 ÷ 25% = 40. If your calculator does not have a portion 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. Determining percentages can be an easy task.
