If you've ever found yourself staring at a half-eaten pie, questioning how the portion that's left compares to the size of the initial pie, congratulations: You've been pondering percentages. Although technically the term "portion" refers to a part out of 100, in real-world terms it truly 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 utilize a calculator to quickly work out portions.
The three terms in a portion calculation 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 percentage. In the math world, exercising percentages normally means that a person 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 percentage (25) and the entire (40 ), so the missing term is the part. Utilizing the same reasoning, 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 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 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%.

If the left out term is the part, utilize the calculator to increase the whole by the percentage to identify the answer. If your calculator has a portion button, the estimation is as follows: 40 x 25% = 10. If your calculator does not have a portion button, you must first divide the percentage 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 identify the answer. If your calculator has a percentage button, the computation is as follows: 10 ÷ 25% = 40. If your calculator does not have a percentage button, you should 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 portions can be a simple job.
