To solve $5 + \frac{4}{5}$, you need to combine the integer and the fraction:

1. Convert the integer 5 to a fraction with the same denominator as $\frac{4}{5}$:
   $5 = \frac{5 \times 5}{5} = \frac{25}{5}$.

2. Add the fractions:
   $\frac{25}{5} + \frac{4}{5} = \frac{25 + 4}{5} = \frac{29}{5}$.

So, $5 + \frac{4}{5} = \frac{29}{5}$.

If you want it as a mixed number:
$\frac{29}{5} = 5 \frac{4}{5}$.
