$2\frac{3}{4}-1\frac{1}{2}=2\frac{3}{4}-1\frac{2}{4}=1\frac{1}{4}$

$5\frac{1}{3}-4\frac{5}{6}=5\frac{2}{6}-4\frac{5}{6}=4\frac{8}{6}-4\frac{5}{6}=\frac{3}{6}=\frac{1}{2}$

$3\frac{1}{4}-2\frac{5}{8}=3\frac{2}{8}-2\frac{5}{8}=2\frac{10}{8}-2\frac{5}{8}=\frac{5}{8}$

$4\frac{1}{6}-1\frac{2}{3}=4\frac{1}{6}-1\frac{4}{6}=3\frac{7}{6}-1\frac{4}{6}=2\frac{3}{6}=2\frac{1}{2}$
