A board game uses a triangular piece measuring 3 inches on each side. The travel version of the game uses a triangle in a proportional relationship to the original. It measures 0.5 inches on each side. Identify the scale factor used to create the travel version.
A. 1/6
B. -1/6
C. 3.5
D. 6
To find the scale factor, we divide the length of the side of the travel version by the length of the side of the original version:
Scale factor = (length of travel version) / (length of original version)
Scale factor = 0.5 inches / 3 inches
Scale factor = 1/6
Therefore, the scale factor used to create the travel version is 1/6.
The answer is A. 1/6.
