Average of Percentages Example
Example Problem #1:
First, gather all of the percentages together. For this example, the percentages are 10%, 25%, 12%, and 3%.
Next, sum all of the percentages together. Adding the values from above together yields:
= 10 + 25 + 12 + 3 = 50%.
Next, determine the total number of percentages. For this example, there were 4 percentages added together.
Finally, calculate the average of the percentages using the formula above:
AV % = X1 + X2 + X... / #
AV % = 50%/ 4
AV % = 12.5%
