ANSWER

$\frac{a + 3}{8}$

EXPLANATION

We want to simplify

$\frac{a + 3}{a} \div \frac{8}{a}$

We multiply the first fraction by the reciprocal of the second fraction to obtain,

$\frac{a + 3}{a} \times \frac{a}{8}$

We cancel the common factors to get,

$\frac{a + 3}{1} \times \frac{1}{8}$

This gives us,

$\frac{a + 3}{8}$
