6) Scale factor of $K$ to $L$ is $\quad 2$ Scale factor of $L$ to $K$ is $1 / 2$ 8)

Step 1 ：The scale factor from K to L is given as 2. This means that L is twice the size of K.

Step 2 ：Therefore, the scale factor from L to K would be the reciprocal of the scale factor from K to L.

Step 3 ：This is because the scale factor is a ratio that compares the sizes of two similar figures.

Step 4 ：If one figure is twice the size of the other, then the smaller figure is half the size of the larger one.

Step 5 ：So, the scale factor of L to K is \(\frac{1}{2}\) or 0.5.

Step 6 ：Final Answer: The scale factor of L to K is \(\boxed{0.5}\)
