Answer:
1/2
Explanation:
You need to see how much times bigger or smaller the shape is after it's changed, that's the scale factor
The dialated image (blue one where it says J'K'T'P') seems like half the size of the black one, so we'll say the scale factor is half or 1/2 (if it's double then the scale factor is 2, for triple, it's 3)
