1. Выполните действия: 1) 6 + 5/13; 2) 6/57 + 4; 3) 6 4/9 + 5 2/9; 4) 11 8/11 − 3 5/11; 5) 8 7/18 + 7 5/18 − 4 11/18; 6) 13 6/10 − 5 3/10 + 16.

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

Ответ: 1) \(6\frac{5}{13}\); 2) \(4\frac{2}{19}\); 3) \(11\frac{2}{3}\); 4) \(8\frac{3}{11}\); 5) \(10\frac{1}{18}\); 6) \(24\frac{3}{10}\).
