How to Get the Average of Decimals


Finding an average of a set of numbers is also known as finding the mean. The only difference between decimals and whole numbers is that decimals represent a portion of a whole number, which may or not be combined with a whole number itself. If you want to find the average of a set of decimals, you only need to use basic mathematical skills such as adding and dividing.

Things You'll Need

  • Calculator
  • Add the list of decimals. For example, consider the following list: 0.45, 1.6, 2.9 and 0.84. Added together, these values equal 5.79.

  • Count the number of decimals in the set that you added. In this example, you added four decimal figures.

  • Divide the total from Step 1 by the number of decimals in your set (as determined in Step 2). In this example, you would divide 5.79 by 4 to get 1.4475. This is the average for your set.
