52. Выполните вычитание: 1) 6 1/14 − 1/7; 2) 8 9/40 − 6 13/50; 3) 5 5/6 − 2 6/7; 4) 9 7/34 − 1 29/102; 5) 8 3/8 − 5 5/6; 6) 7 13/36 − 3 25/54.

1. \(6\frac{1}{14}-\frac{1}{7}=6\frac{1}{14}-\frac{2}{14}=5\frac{13}{14}\).
2. \(8\frac{9}{40}-6\frac{13}{50}=2+\frac{45-52}{200}=1\frac{193}{200}\).
3. \(5\frac{5}{6}-2\frac{6}{7}=3+\frac{35-36}{42}=2\frac{41}{42}\).
4. \(9\frac{7}{34}-1\frac{29}{102}=8+\frac{21-29}{102}=7\frac{47}{51}\).
5. \(8\frac{3}{8}-5\frac{5}{6}=3+\frac{9-20}{24}=2\frac{13}{24}\).
6. \(7\frac{13}{36}-3\frac{25}{54}=4+\frac{39-50}{108}=3\frac{97}{108}\).

Ответ: 1) \(5\frac{13}{14}\); 2) \(1\frac{193}{200}\); 3) \(2\frac{41}{42}\); 4) \(7\frac{47}{51}\); 5) \(2\frac{13}{24}\); 6) \(3\frac{97}{108}\).
