Ответ:
- \(6+\frac{5}{18}=6\frac{5}{18}\).
- \(\frac{6}{57}+4=\frac{2}{19}+4=4\frac{2}{19}\).
- \(6\frac{4}{9}+5\frac{2}{9}=11\frac{6}{9}=11\frac{2}{3}\).
- \(11\frac{8}{11}-3\frac{5}{11}=8\frac{3}{11}\).
- \(8\frac{7}{18}+7\frac{5}{18}-4\frac{11}{18}=15\frac{12}{18}-4\frac{11}{18}=11\frac{1}{18}\).
- \(13\frac{6}{10}-5\frac{3}{10}+16\frac{1}{10}=8\frac{3}{10}+16\frac{1}{10}=24\frac{4}{10}=24\frac{2}{5}\).
Ответ: 1) \(6\frac{5}{18}\); 2) \(4\frac{2}{19}\); 3) \(11\frac{2}{3}\); 4) \(8\frac{3}{11}\); 5) \(11\frac{1}{18}\); 6) \(24\frac{2}{5}\).
