Вычитание дробей

• 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) $$8-4\frac{7}{8} = 7\frac{8}{8} - 4\frac{7}{8} = 3\frac{1}{8}$$
• е) $$10-1\frac{1}{9} = 9\frac{9}{9} - 1\frac{1}{9} = 8\frac{8}{9}$$
