To simplify, we first convert the mixed numbers to improper fractions:
$$12 \frac { 4 } { 5 } - 6 \frac { 9 } { 10 } = \frac{64}{5} - \frac{69}{10}.$$
Next, we find a common denominator and combine the fractions:
\begin{align*}
\frac{128}{10} - \frac{69}{10} &= \frac{128-69}{10} \
&= \frac{59}{10}.
\end{align*}
Finally, we convert the improper fraction back to a mixed number:
$$\frac{59}{10} = 5 \frac {9}{10}.$$
Therefore, the answer is choice C, $5 \frac {9}{10}$.
