First, convert the mixed numbers to improper fractions: $6 \frac{3}{4} = \frac{27}{4}$ and $6 \frac{9}{20} = \frac{129}{20}$. To add them, find a common denominator, which is 20 in this case. So, $\frac{27}{4} = \frac{135}{20}$. Adding $\frac{135}{20} + \frac{129}{20} = \frac{264}{20}$, which simplifies to $13 \frac{4}{20}$ or $13 \frac{1}{5}$ in lowest terms.
