Ответ:
- \(\frac{5}{8}+\frac{3}{14}=\frac{35}{56}+\frac{12}{56}=\frac{47}{56}\).
- \(\frac{11}{12}-\frac{7}{18}=\frac{33}{36}-\frac{14}{36}=\frac{19}{36}\).
- \(4\frac{2}{5}+3\frac{7}{15}=7+\frac{6}{15}+\frac{7}{15}=7\frac{13}{15}\).
- \(8\frac{1}{6}-5\frac{5}{9}=3+\frac{1}{6}-\frac{5}{9}=3+\frac{3}{18}-\frac{10}{18}=2\frac{11}{18}\).
Ответ: а) \(\frac{47}{56}\); б) \(\frac{19}{36}\); в) \(7\frac{13}{15}\); г) \(2\frac{11}{18}\).
