Ответ:

  1. а) \(1-\frac{5}{8}=\frac{3}{8}\).
  2. б) \(10-1\frac{1}{9}=8\frac{8}{9}\).
  3. в) \(9\frac{5}{6}-2\frac{3}{4}=7\frac{1}{12}\).
  4. г) \(3\frac{3}{10}-1\frac{7}{15}=1\frac{5}{6}\).
  5. д) \(7\frac{5}{18}-1\frac{7}{12}=5\frac{5}{18}-1\frac{7}{12}=3\frac{25}{36}\).
  6. е) \(5\frac{3}{24}-1\frac{1}{21}=4\frac{1}{8}-1\frac{1}{21}=4\frac{13}{168}\).
