The average of 5, 7, 12, and 12, is (5 + 7 + 12 + 12)/4.
(5 + 7 + 12 + 12)/4 = 36/4 = 9.
The average is 9.

To find the average, or mean, you add up all the numbers and divide the sum by the total number of numbers you added up.

5, 7, 12, 12
Add these numbers up ⇒ 5 + 7 + 12 + 12 = 36.
Divide 36 by the number of numbers added up, 4. ⇒ 36 ÷ 4 = 9

The mean of the numbers is 9.
