a) $$1-\frac{5}{8} = \frac{8}{8} - \frac{5}{8} = \frac{3}{8}$$
б) $$1-\frac{1}{6} = \frac{6}{6} - \frac{1}{6} = \frac{5}{6}$$
в) $$6-\frac{2}{5} = \frac{30}{5} - \frac{2}{5} = \frac{28}{5} = 5\frac{3}{5}$$
г) $$5-\frac{2}{3} = \frac{15}{3} - \frac{2}{3} = \frac{13}{3} = 4\frac{1}{3}$$
д) $$8-4\frac{7}{8} = 8-\frac{39}{8} = \frac{64}{8} - \frac{39}{8} = \frac{25}{8} = 3\frac{1}{8}$$
е) $$10-1\frac{1}{9} = 10-\frac{10}{9} = \frac{90}{9} - \frac{10}{9} = \frac{80}{9} = 8\frac{8}{9}$$
