A percentage is subtracted from a number by calculating the percentage in relation to that number and then performing a basic subtraction function.

Full Answer

Before performing the subtraction step, individuals must convert the percentage to a relevant number. First, a person moves the decimal point to the left two places, converting the percentage figure to a number. Thus, 70 percent becomes 0.70. The original number is then multiplied by the percent number: In the example, 200 times 0.70 equals 140.

    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.
