Full Answer

Percentage is a way to express fractions in an easily understood standardized format. The act of dividing a number by its possible whole is essentially that of converting a fraction into a decimal. When that decimal is multiplied by 100, the resulting number is the original fraction with a new denominator of 100. When every fraction is expressed with a common denominator, it allows for easier mental calculations and sets a baseline for quick comparisons.

    How is the equivalent percentage figure for a number determined?

    A:

    To turn a number into its equivalent percentage, a person should move the decimal point two places to the right and then add the percent sign. For example, to turn the number 7 into a percentage, a person would move the decimal point two places to the right, which requires the addition of two 0s after the 7, and the percentage is expressed as 700 percent. In the case of .35, moving the decimal point two places to the right expresses the number in its percentage form as 35 percent.
