Solve Mixed Number Addition: 1 + 2½ Step by Step

To solve the problem $1 + 2\frac{1}{2}$, follow these steps:

• Step 1: Identify the numbers to add: $1$ is a whole number, and $2\frac{1}{2}$ is a mixed number consisting of the whole part $2$ and the fractional part $\frac{1}{2}$.
• Step 2: Add the whole numbers: $1 + 2 = 3$.
• Step 3: Keep the fractional part from the mixed number unchanged: $\frac{1}{2}$.
• Step 4: Combine the result of the whole numbers' addition with the fractional part: $3 + \frac{1}{2} = 3\frac{1}{2}$.

Therefore, the solution to the problem $1 + 2\frac{1}{2}$ is $3\frac{1}{2}$.
