To add $\frac{5}{12} + \frac{7}{8}$, we need a common denominator.

1. The denominators are $12$ and $8$. The least common denominator (LCD) is $24$.

2. Rewrite each fraction with the denominator $24$: $\frac{5}{12} = \frac{10}{24}, \quad \frac{7}{8} = \frac{21}{24}$

3. Add the fractions: $\frac{10}{24} + \frac{21}{24} = \frac{31}{24}$

4. Simplify if needed. $\frac{31}{24}$ is an improper fraction, and as a mixed number: $\frac{31}{24} = 1 \frac{7}{24}$

Final Answer: $\frac{31}{24}$ or $1 \frac{7}{24}$.
