AFOQT Practice Test

The formula for determining percentages can be expressed as which of the following?

1. Whole = Part x Percent

2. Part = Whole x Percent

3. Percent = Whole x Part

4. Part = Percent x Whole

The correct answer is: Part = Whole x Percent

The correct answer is based on the standard equation used to determine a part in relation to a whole and its percentage. To break it down, the formula can be expressed mathematically as Part = Whole x Percent, where the "Whole" represents the total quantity, the "Part" is the portion of that total, and "Percent" indicates the fraction of the whole that the part represents, often expressed as a decimal (e.g., 20% is expressed as 0.2). This formula shows how to find a specific amount (the part) when you know the total amount (the whole) and the percentage that the part represents. For instance, if you have a whole of 100 and you want to find out what 20% of that whole is, you would calculate 100 x 0.20, resulting in a part of 20. In contrast, the other options do not correctly define the relationship needed to find the part based on the whole and the percent. They appear to misalign the variables in this percentage calculation, thus making them unsuitable for expressing how to determine percentages effectively.
