Answer:
1/3
Step-by-step explanation:
Look at two corresponding lengths that are easy to measure.
BC and B'C' are both along horizontal lines, so you can easily count squares to find their lengths.
BC = 3
B'C' = 1
B'C' is the image, and BC is the original.
The scale factor is obtained by dividing a length of the image by the corresponding length of the original.
scale factor = B'C'/BC = 1/3
