If the question is "What percentage of 40 is 10?" you have the part (10) and the entire (40 ), so the left out term is the percentage.

Utilizing the very same logic, if the concern is "10 is 25 percent of what?" the the term is the entire.
If the left out term is the percentage, divide the part by the whole using your calculator to figure out 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 response by 100 to determine the percentage: 0.25 x 100 = 25%.
