Chapter 1.2, Problem 11P

For each number line in Figure 1.44 (a)-(d), draw three copies of the line. Use your number lines to show three different ways to label the tick marks in the original line. In each case, your labeling should fit with the structure of the base-ten system and the fact that the tick marks at the ends of the number lines are longer than the other tick marks.
