Question

What is the average of 3%, 7%, 10%, and 16% ?

Answer 1

Answer:

Example 1: Find the average grade in your math class. There are 10 students, and so far their cumulative percentage grades are: 77, 62, 89, 95, 88, 74, 82, 93, 79 and 82.

Start by adding up all of the students' scores:

77 + 62 + 89 + 95 + 88 + 74 + 82 + 93 + 79 + 82 = 821

Next, divide that total by the number of scores you added. (You could count them, or you could just take note that the original problem tells you there are 10.)

821 ÷ 10 = 82.1

The result, 82.1, is the average score in your math class.
