We have the following:
what we must do is pass from fractional form to decimal form to each one
[tex]\begin{gathered} \frac{1}{2}=0.5 \\ \frac{3}{4}=0.75 \\ \frac{7}{8}=0.875 \end{gathered}[/tex]Therefore
The smallest wrench is 0.5 inch and the largest is 0.875 inch
The smallest wrench is 1/2 inch and the largest is 7/8 inch
