To find the scale factor used to create the travel version of the triangular piece, we compare the dimensions of the original triangle to the dimensions of the travel version.
The original triangle has a side measurement of 3 inches, and the travel version has a side measurement of 0.5 inches.
The scale factor can be calculated by dividing the size of one triangle by the size of the other:
\[ \text{Scale Factor} = \frac{\text{Size of Travel Version}}{\text{Size of Original}} = \frac{0.5 \text{ inches}}{3 \text{ inches}} = \frac{0.5}{3} = \frac{1}{6} \]
So, the scale factor used to create the travel version of the piece is \( \frac{1}{6} \).
