Video Solution

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Identify the given numbers and set up the problem.
  • Step 2: Calculate the sum of the numbers.
  • Step 3: Divide the sum by the total count of numbers to find the average.

Now, let's work through each step:

Step 1: We have three numbers: 9 9 , 4 4 , and 8 8 . Our task is to find their average.

Step 2: Calculate the sum of these numbers:
9+4+8 9 + 4 + 8

First, add 9 9 and 4 4 :
9+4=13 9 + 4 = 13

Next, add 13 13 to 8 8 :
13+8=21 13 + 8 = 21

So, the sum of the numbers is 21 21 .

Step 3: Divide the sum by the number of numbers to find the average:
Average=213 \text{Average} = \frac{21}{3}

Calculating the division:
21÷3=7 21 \div 3 = 7

Thus, the average of the numbers 9 9 , 4 4 , and 8 8 is 7 7 .

Therefore, the solution to the problem is 7 7 .
