# Will calculate percentages Ever Rule the World? 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 contemplating portions. Although technically the term "percentage" describes a portion out of 100, in real-world terms it truly deals with 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 easily exercise percentages.
The three terms in a portion computation are the part, the entire, 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 implies that one of those terms is missing out on and you need to discover it. If the concern is "What percentage of 40 is 10?" you have the part (10) and the entire (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 whole (40 ), so the missing term is the part. Utilizing the exact same logic, if the question 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 identify the percentage. If your calculator does not have such a button, multiply your previous answer by 100 to figure out 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 identify 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 percentage 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 portion to figure out the response. If your calculator has a portion button, the estimation is as follows: 10 ÷ 25% = 40. If your calculator does not have a portion button, you need to divide the portion by 100 prior to finishing the computation: 25 ÷ 100 = 0.25.
