Work Step by Step
a) 3 $\frac{1}{4}$ in - 1 $\frac{3}{8}$ in - 1 $\frac{5}{8}$ in = $\frac{1}{4}$ in
b) 1 $\frac{3}{8}$ in + $\frac{13}{16}$ in + 1 $\frac{1}{4}$ in + 1 $\frac{7}{8}$ in + 1 $\frac{5}{8}$ in + $\frac{15}{16}$ in + $\frac{1}{4}$ in + $\frac{15}{16}$ in + 1 $\frac{3}{8}$ in + 1 $\frac{7}{8}$ in = 12 $\frac{5}{16}$ in
