Percentage of Wage Increase

Percent is many times used to show change. It can be used to show percentage of increase or percentage of decrease. This is a concept that GED math students need to be able to demonstrate.

If you remember some simple key ideas, and practice a variety of problems, it will be easier to solve quickly on the GED math test.

  1. Determine the amount of change.  The amount of change is the difference between the new number and the original number.
  2. Divide the amount of change by the original number.  This will result in a decimal number.
  3. Change the decimal number to a percent.
  4. Remember that percent of increase CAN be greater than 100%.

New number – original number/ original number = decimal number = percentage of increase or decrease.
