Вычислите: 1) \(1\frac{12}{14}+\frac{2}{14}\); 2) \(5-2\frac{34}{43}\); 3) \(24\frac{12}{17}-2\frac{13}{17}\).

1. \[1\frac{12}{14}+\frac{2}{14}=1\frac{14}{14}=2\]
2. \[5-2\frac{34}{43}=2\frac{43}{43}-2\frac{34}{43}=\frac{9}{43}\]
3. \[24\frac{12}{17}-2\frac{13}{17}=23\frac{29}{17}-2\frac{13}{17}=21\frac{16}{17}\]

Ответ: 1) 2; 2) \(\frac{9}{43}\); 3) \(21\frac{16}{17}\).
