58. Выполни действия: 1) 4/11 + 3/11 − 2/11; 2) 4 2/5 + 4/5; 3) 1 − 8/13; 4) 7 2/17 − 5 4/17.

1. \(\frac{4}{11}+\frac{3}{11}-\frac{2}{11}=\frac{4+3-2}{11}=\frac{5}{11}\).
2. \(4\frac{2}{5}+\frac{4}{5}=4+\frac{6}{5}=5\frac{1}{5}\).
3. \(1-\frac{8}{13}=\frac{13}{13}-\frac{8}{13}=\frac{5}{13}\).
4. \(7\frac{2}{17}-5\frac{4}{17}=\frac{121}{17}-\frac{89}{17}=\frac{32}{17}=1\frac{15}{17}\).

Ответ: 1) \(\frac{5}{11}\); 2) \(5\frac{1}{5}\); 3) \(\frac{5}{13}\); 4) \(1\frac{15}{17}\).
