## Solving for "c": 1 1/4 + c = 2 3/4

This problem involves solving for an unknown variable "c" in an equation involving fractions. Here's how to approach it:

**1. Convert Mixed Numbers to Improper Fractions:**

**1 1/4:**(1 x 4 + 1) / 4 = 5/4**2 3/4:**(2 x 4 + 3) / 4 = 11/4

**2. Rewrite the Equation:**

The equation now becomes: 5/4 + c = 11/4

**3. Isolate "c":**

To get "c" by itself, subtract 5/4 from both sides of the equation:

5/4 + c - 5/4 = 11/4 - 5/4

**4. Simplify:**

This leaves us with: c = 6/4

**5. Simplify to Mixed Number (Optional):**

The fraction 6/4 can be simplified to 1 2/4, which further simplifies to **1 1/2**.

**Therefore, the solution is c = 1 1/2**
