To find the total length of the wire needed, you'll need to add the three lengths together.
The lengths of the wires are:
- \( \frac{2}{17} \) cm
- \( \frac{5}{17} \) cm
- \( \frac{8}{17} \) cm
Now, add these fractions:
\[ \frac{2}{17} + \frac{5}{17} + \frac{8}{17} = \frac{2 + 5 + 8}{17} = \frac{15}{17} \text{ cm} \]
Thus, the total amount of wire used for the part is \( \frac{15}{17} \) cm.
