To be able to plot the points, first, we have to convert the given mixed numbers to a sum and write that sum in a convenient form.
Converting the given mixed numbers, we get:
[tex]2\frac{1}{2}=2+\frac{1}{2}\text{.}[/tex]
Since the distance between the numbers in the given number line is graded in eights, we can rewrite the above number as:
[tex]2+\frac{1}{2}=2+\frac{4}{8}\text{.}[/tex]
Now,
[tex]-1\frac{3}{4}=-(1+\frac{3}{4})=-(1+\frac{6}{8}).[/tex]
Therefore, the last point must be 6/8 to the left of -1.
