Выполним вычитание.

a) \(1 - \frac{3}{4} = \frac{4}{4} - \frac{3}{4} = \frac{1}{4}\)

б) \(2 - \frac{5}{6} = \frac{12}{6} - \frac{5}{6} = \frac{7}{6} = 1\frac{1}{6}\)

в) \(9 - \frac{11}{12} = \frac{108}{12} - \frac{11}{12} = \frac{97}{12} = 8\frac{1}{12}\)

г) \(7 - 1\frac{7}{8} = 6\frac{8}{8} - 1\frac{7}{8} = 5\frac{1}{8}\)

д) \(5 - 2\frac{2}{5} = 4\frac{5}{5} - 2\frac{2}{5} = 2\frac{3}{5}\)

e) \(6 - 5\frac{5}{8} = 5\frac{8}{8} - 5\frac{5}{8} = \frac{3}{8}\)

ж) \(8\frac{3}{11} - 4 = 4\frac{3}{11}\)

з) \(5\frac{7}{15} - 3\frac{2}{20} = 5\frac{28}{60} - 3\frac{6}{60} = 2\frac{22}{60} = 2\frac{11}{30}\)

Ответ: a) \(\frac{1}{4}\); б) \(1\frac{1}{6}\); в) \(8\frac{1}{12}\); г) \(5\frac{1}{8}\); д) \(2\frac{3}{5}\); e) \(\frac{3}{8}\); ж) \(4\frac{3}{11}\); з) \(2\frac{11}{30}\)
