Answer:
you need to focus on the equality measure left to right or up or down and see if it is 2 x, 3 x or 4 x in one direction.
IF say it appears to be 2 x one direction and 2 x another direction then the answer of scale factor is 1:2
As each direction has dilated from 1 to 2. (= 2x)
Therefore, you would need to answer in accordance ie) 1:2 would be the answer.

We use the larger numver first if it is asking what is the contraction (opposite to dilate) scale factor = 2:1
