Simplify the following expression: (17/34) (6/12) (1/8)

For the first fraction, $34 = 2 \times 17$, so $\frac{17}{34} = \frac{1}{2}$.
For the second fraction, $12 = 2 \times 6$, so $\frac{6}{12} = \frac{1}{2}$.
The third fraction $\frac{1}{8}$ is already in its simplest form.

The final answer is $\frac{1}{32}$.
