The 3 terms in a percentage estimation are the part, the whole, and the percentage. 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 portions normally suggests that one of those terms is missing and you require to find it. If the question is "What percentage of 40 is 10?" you have the part (10) and the whole (40 ), so the omitted term is the percentage. If the question is "What is 25 percent of 40?" you have the portion (25) and the entire (40 ), so the missing term is the part. Utilizing the very same logic, if the question 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 determine the response. For the example equation, this is 10 ÷ 40 = 0.25. If your calculator has a portion button, press it to identify the portion. If your calculator does not have such a button, multiply your previous response by 100 to identify the percentage: 0.25 x 100 = 25%.
