ANSWER
5/6
Step-by-step explanation
We want to find the scale factor from drawing 2 to drawing 1.
The scale factor can be found by dividing the length of the corresponding side of the image by that of the pre-image.
This means that we have to divide the length of side of drawing 1 by drawing 2.
The length of side of drawing 1 is 10 and that of drawing 2 is 12.
Therefore, we have that the scale factor is:
That is the scale factor.
