  1. Write down the percentages

    In order to stay organized, it is helpful to have the list of the percentages written down on a piece of paper in front of you. This allows for the process of finding the average easier as you make calculations.

  2. Change each percentage to a decimal

    To simplify calculations, change each percentage to a decimal. This is done by individually dividing the percentages by 100. You may find using your calculator easier and more accurate than performing the math in your head, but either method works. Write down the decimal number after each percentage on your paper.

  3. Add the total number of percentages

    Count how many percentages you are working with and record this number on your paper for ease of reference. This number is important in finding an average percent.

  4. Calculate the total of the percentages

    Add the decimals of all the percentages together. This number will be used along with the number of individual percentages to find the average.

  5. Find the average percentage

    Take the total amount of the decimals, and divide that number by the total number of individual percentages. This gives you the average percentage in decimal form.

  6. Change from a decimal to a percent

    Take the average percentage in decimal form, and multiply the number by 100. This gives you the average percentage in percent form.
