UpStudy AI · Accepted Answer

To solve the addition $$ \frac{1}{2} + \frac{7}{8} $$, follow these steps:

1. **Find a Common Denominator**

The denominators are 2 and 8. The least common denominator (LCD) is **8**.

2. **Convert Fractions to Have the Same Denominator**

- Convert $$ \frac{1}{2} $$ to a fraction with denominator 8:
     $$
     \frac{1}{2} = \frac{1 \times 4}{2 \times 4} = \frac{4}{8}
     $$
   
   - $$ \frac{7}{8} $$ already has the denominator 8.

3. **Add the Numerators**

$$
   \frac{4}{8} + \frac{7}{8} = \frac{4 + 7}{8} = \frac{11}{8}
   $$

4. **Simplify the Result (If Desired)**

$$ \frac{11}{8} $$ is an improper fraction and can be converted to a mixed number:
   
   $$
   \frac{11}{8} = 1 \frac{3}{8}
   $$
   
   This is because 8 goes into 11 once with a remainder of 3.

**Answer:** 
$$
\frac{1}{2} + \frac{7}{8} = \frac{11}{8} \quad \text{or} \quad 1 \frac{3}{8}
$$
$$ \frac{1}{2} + \frac{7}{8} = \frac{11}{8} \quad \text{or} \quad 1 \frac{3}{8} $$
