- \(5-2\frac{3}{8}=4\frac{8}{8}-2\frac{3}{8}=2\frac{5}{8}\).
- \(4\frac{1}{7}+2\frac{4}{7}=6\frac{5}{7}\).
- \(6\frac{2}{9}-3\frac{5}{9}=5\frac{11}{9}-3\frac{5}{9}=2\frac{6}{9}=2\frac{2}{3}\).
- \(10\frac{3}{11}-4\frac{7}{11}=9\frac{14}{11}-4\frac{7}{11}=5\frac{7}{11}\).
Ответ: а) \(2\frac{5}{8}\); б) \(6\frac{5}{7}\); в) \(2\frac{2}{3}\); г) \(5\frac{7}{11}\).
