Q:

How do you add a percentage to a number?

A:

To add a percentage to a number, change the percentage to a decimal value, and add one to the value. Multiply the number by the result.

  1. Convert to a decimal value

    Convert a percentage to a decimal value by dividing it by 100 or moving the decimal to the left two places. For example, 19 percent equals 0.19.

  2. Add one

    Add one to the decimal number. For example, 0.19 + 1 = 1.19.

  3. Multiply by the result

    Multiply the number by one plus the decimal value. For example, 250 x 1.19 = 297.5. This result means that 19 percent of 250 added to 250 equals 297.5.
