# What Hollywood Can Teach Us About percentage calculator 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 portion out of 100, in real-world terms it actually deals with how a part of something-- say, that half-eaten pie-- compares to the entire. For example, half is equal to half, or 50 out of 100. You can use a calculator to quickly work out percentages.
The 3 terms in a percentage estimation are the part, the whole, and the portion. In the formula: 25% of 40 = 10, 10 is the part, 40 is the whole, and 25 is the portion. In the math world, working out portions typically suggests that one of those terms is missing and you require to find it. If the question is "What portion of 40 is 10?" you have the part (10) and the entire (40 ), so the omitted term is the percentage. If the concern is "What is 25 percent of 40?" you have the portion (25) and the whole (40 ), so the missing term is the part. Using the very 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 using 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 portion: 0.25 x 100 = 25%.

If the omitted term is the part, use the calculator to increase the whole by the portion 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 need to 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 portion button, you should divide the portion by 100 before completing the computation: 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 task. There are many portion calculators online that can assist with job by just searching for "percentage calculator." However, there might be a time when (nevertheless, not likely it sounds) you may need to be able to calculate portions with no digital support.

Cent is an old European word with French, Latin, and Italian origins indicating "hundred". So, percent is translated directly to "per hundred." If you have 87 percent, you actually have 87 per 100. If it snowed 13 times in the last 100 days, it snowed 13 percent of the time.
