## Solving for "c" in the Equation 1 1/4 + c = 2 3/4

This problem involves solving for an unknown variable, "c," in a simple addition equation. Here's how to solve it:

**1. Understanding the Equation**

The equation states that 1 1/4 plus some unknown value "c" equals 2 3/4.

**2. Isolating "c"**

To find the value of "c," we need to isolate it on one side of the equation. We can do this by subtracting 1 1/4 from both sides:

```
1 1/4 + c = 2 3/4
- 1 1/4 - 1 1/4
-------------
c = 1 1/2
```

**3. Finding the Answer**

Therefore, the value of "c" that makes the equation true is **1 1/2**.

**4. Verification**

To verify our answer, we can substitute 1 1/2 for "c" in the original equation:

```
1 1/4 + 1 1/2 = 2 3/4
```

We can easily see that this equation is true, confirming our answer.
