# How Did We Get Here? The History of percent calculator Told Through Tweets

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.

The three 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 math world, exercising percentages usually indicates that one of those terms is missing and you require to discover 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 logic, 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 identify the answer. For the example equation, this is 10 ÷ 40 = 0.25. If your calculator has a portion button, press it to figure out 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%.

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 determine the answer. If your calculator has a percentage button, the calculation is as follows: 10 ÷ 25% = 40. If your calculator does not have a percentage button, you must divide the portion by 100 before finishing the estimation: 25 ÷ 100 = 0.25.
