Add `(11)/(8) and (-6)/(8).`

Answer

To solve the problem of adding \(\frac{11}{8}\) and \(-\frac{6}{8}\), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the fractions**: We have \(\frac{11}{8}\) and \(-\frac{6}{8}\).

2. **Check the denominators**: Both fractions have the same denominator, which is 8. Since the denominators are the same, we can directly add the numerators.

3. **Set up the addition**: We will write the addition as:
\[ \frac{11}{8} + \left(-\frac{6}{8}\right) = \frac{11}{8} - \frac{6}{8} \]

4. **Combine the numerators**: Now we can combine the numerators:
\[ 11 - 6 = 5 \]

5. **Write the result**: The result will be:
\[ \frac{5}{8} \]

6. **Final answer**: Therefore, the sum of \(\frac{11}{8}\) and \(-\frac{6}{8}\) is:
\[ \frac{5}{8} \]
