Of the 16 small intervals indicated from 0 to 1 inch, the ant spans 14 of them, so
[tex]\dfrac{14}{16} = \dfrac{7}{8} \textrm{ inches} = 0.875 \textrm{ in}[/tex]
How is 7/8 equal to 0.875?
Since 125(8)=1000 and 125(7)=875 we know
[tex]\dfrac{7}{8} = \dfrac{7 \cdot 125}{8 \cdot 125} = \dfrac{875}{1000} = 0.875[/tex]
