Estimate: 2 inches Exact: $2\frac{1}{2}$ inches
From the table, we see that the maximum jaw capacity is $3\frac{3}{8}$, and the minimum is $7/8$. We subtract and find the difference. Estimate: $3-1=2$ inches Exact: $\displaystyle 3\frac{3}{8}-\frac{7}{8}=2\frac{11}{8}-\frac{7}{8}=2\frac{4}{8}=2\frac{1}{2}$ inches
