What is the average of 4, 8, and 15?

  1. 8

  2. 10

  3. 9

  4. 12

The correct answer is: 9

To find the average of a set of numbers, you add them together and divide by the number of values in the set. In this case, the numbers are 4, 8, and 15. First, add the numbers together: 4 + 8 + 15 = 27. Next, divide the sum by the number of values, which is 3: 27 ÷ 3 = 9. Thus, the average of 4, 8, and 15 is 9. This method demonstrates a straightforward application of the formula for calculating the average and shows you how to approach similar problems by following consistent mathematical steps.
