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 one for the original picture if it starts smaller.

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