The length of JK¯¯¯¯¯ is 12 units.

What is the length of the image of the line segment after a dilation with a scale factor of 2/5?

Assuming you mean 25%, the answer will be 25/100 * 12, which is 3.

Thanks, superman...!!!

But...if the scale factor is truly 25....the image is now 25 * 12 = 300 units long.

It was soppose to be 2/5 instead of 25. Im sorry!!

(2/5) *12 = 24 / 5 = 4 + 4/5 = 4.8
