You can solve this problem using the process of elimination. Since -0.135 is less than -0.1 and greater than -0.2, we know that A and B aren't the correct. They are less than -0.2. To choose between C and D, we know that -0.135 is greater than -0.15, which is the halfway point between -0.1 and -0.2. The number line shows C being less than the halfway point and D being greater. We can deduce that Point D is located at -0.135.
