Answer:

(1)/(2)

Explanation:

It is given that triangle ACB is the preimage and triangle DFE is the image.

We need to find the scale factor of the dilation.

$\text{Scale factor}=\frac{\text{Side of image}}{\text{Corresponding side of preimage}}$

In the given triangles, side AC and DF are corresponding sides.

$\text{Scale factor}=(DF)/(AC)$

$\text{Scale factor}=(6)/(12)$

$\text{Scale factor}=(1)/(2)$

Therefore, the scale factor of the dilation is
.
