7. Show how to "zoom in" on smaller and smaller portions of the number line (Figure 1.4) so that you can plot 5.7183 on each number line. Label the long tick marks on each number line (at the ends) and plot 5.7183 on each number line (in its approximate location). 0 Long ticks: whole numbers Long ticks: tenths Lng ticks: hundredths Long ticks: thousandths + 2 + + 3 5 Figure 1.4: Zooming In on a Number Line 6 11 13 7 8 JA 8. Show how to "zoom in" on smaller and smaller portions of the first number linc in Figure 1.5 until you have "zoomed in" to a portion of the number line on which the long tick marks are thousandths and so that 1.0228 can be plotted on each number line. Plot 1.0228 on each number line.
