See a solution process below:

Explanation:

We can rewrite this as:

$\left(12 + \frac{6}{7}\right) - \left(8 + \frac{3}{7}\right) \implies$

$12 + \frac{6}{7} - 8 - \frac{3}{7} \implies$

$12 - 8 + \frac{6}{7} - \frac{3}{7} \implies$

$\left(12 - 8\right) + \left(\frac{6}{7} - \frac{3}{7}\right) \implies$

$4 + \frac{6 - 3}{7} \implies$

$4 + \frac{3}{7} \implies$

$4 \frac{3}{7}$
