Ответ:
- \(1-\frac{1}{6}=\frac{6-1}{6}=\frac{5}{6}\).
- \(2-\frac{3}{7}=\frac{14-3}{7}=1\frac{4}{7}\).
- \(7-\frac{1}{13}=\frac{91-1}{13}=6\frac{12}{13}\).
- \(6-1\frac{5}{9}=5\frac{9}{9}-1\frac{5}{9}=4\frac{4}{9}\).
- \(9-3\frac{4}{7}=8\frac{7}{7}-3\frac{4}{7}=5\frac{3}{7}\).
- \(5-4\frac{2}{11}=4\frac{11}{11}-4\frac{2}{11}=\frac{9}{11}\).
Ответ: а) \(\frac{5}{6}\); б) \(1\frac{4}{7}\); в) \(6\frac{12}{13}\); г) \(4\frac{4}{9}\); д) \(5\frac{3}{7}\); е) \(\frac{9}{11}\).
