Find the Arithmetic Mean: Three Numbers with Sum of 9

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

• Step 1: Identify the given information: The sum of the three numbers is $9$.
• Step 2: Apply the formula for average.
• Step 3: Perform the necessary calculation to find the average.

Now, let's work through each step:
Step 1: The problem gives us the sum of the three numbers as $9$.
Step 2: We'll use the formula for average:
$\text{Average} = \frac{\text{Sum of the numbers}}{\text{Number of values}}$ Step 3: Plugging in our values, we have: $\text{Average} = \frac{9}{3} = 3$

Therefore, the solution to the problem is $3$.
