How do you figure your math average by percents?

Answer 1

First, you add up your percents; e.g. 80 + 90 + 70 = 260.

Then, you divide that sum by the number of percent values you added; e.g. there were three percent values in the above example, 80, 90, and 70, so you would divide the above sum by three, 260 / 3 = 86.666.
