Calculate the Average: Finding the Mean of 11 and 7

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

• Step 1: Add the two numbers.
• Step 2: Divide the sum by 2 to find the average.

Now, let's work through each step:
Step 1: Add 11 and 7. This gives $11 + 7 = 18$.
Step 2: Divide the sum by 2. Thus, the average is $\frac{18}{2} = 9$.

Therefore, the solution to the problem is $9$.
