Chapter 1.2, Problem 7P

Draw a number line on which the long tick marks are whole numbers and on which 7.0028 can be plotted (in its approximate location). Show how to zoom in on smaller and smaller portions of the number line (as in Figure 1.22 and Class Activity 1 F, part 1) until you have zoomed in to a portion of the number line in which the long tick marks are thousandths and so that 7.0028 can be plotted on each number line. Label the long tick marks on each number line, and plot 7.0028 on each number line (in its approximate location).
