Ответ:
- а) \(10-\frac{5}{9}=9\frac{9}{9}-\frac{5}{9}=9\frac{4}{9}\).
- б) \(12-\frac{5}{9}=11\frac{9}{9}-\frac{5}{9}=11\frac{4}{9}\).
- в) \(11-\frac{12}{13}=10\frac{13}{13}-\frac{12}{13}=10\frac{1}{13}\).
- г) \(2\frac{4}{9}-1\frac{5}{9}=1\frac{13}{9}-1\frac{5}{9}=\frac{8}{9}\).
- д) \(3\frac{2}{5}-2\frac{3}{5}=2\frac{7}{5}-2\frac{3}{5}=\frac{4}{5}\).
- е) \(10\frac{1}{3}-9\frac{2}{3}=9\frac{4}{3}-9\frac{2}{3}=\frac{2}{3}\).
Ответ: а) \(9\frac{4}{9}\); б) \(11\frac{4}{9}\); в) \(10\frac{1}{13}\); г) \(\frac{8}{9}\); д) \(\frac{4}{5}\); е) \(\frac{2}{3}\).
