1. **Problem:** Evaluate $\frac{1}{2}+\frac{1}{2}$.\n2. Use a common denominator. Since the denominators are already the same, add the numerators: $\frac{1}{2}+\frac{1}{2}=\frac{1+1}{2}$.\n3. Simplify the numerator: $\frac{1+1}{2}=\frac{2}{2}$.\n4. Cancel the common factor $2$: $$\frac{\cancel{2}}{\cancel{2}}=1$$\n5. **Final answer:** $1$.
