449. Найдите частное: 1) 6 : 7/9; 2) 16 : 4/11; 3) 13 : 26/29; 4) 7/9 : 5; 5) 9/16 : 6; 6) 1 5/9 : 1 8/27; 7) 2 10/13 : 3 3/26; 8) 2 4/7 : 1 1/35.

1. \(6:\frac{7}{9}=6\cdot\frac{9}{7}=\frac{54}{7}=7\frac{5}{7}\).
2. \(16:\frac{4}{11}=16\cdot\frac{11}{4}=44\).
3. \(13:\frac{26}{29}=13\cdot\frac{29}{26}=\frac{29}{2}=14\frac{1}{2}\).
4. \(\frac{7}{9}:5=\frac{7}{9}\cdot\frac{1}{5}=\frac{7}{45}\).
5. \(\frac{9}{16}:6=\frac{9}{16}\cdot\frac{1}{6}=\frac{3}{32}\).
6. \(1\frac{5}{9}:1\frac{8}{27}=\frac{14}{9}:\frac{35}{27}=\frac{14}{9}\cdot\frac{27}{35}=\frac{6}{5}=1\frac{1}{5}\).
7. \(2\frac{10}{13}:3\frac{3}{26}=\frac{36}{13}:\frac{81}{26}=\frac{36}{13}\cdot\frac{26}{81}=\frac{8}{9}\).
8. \(2\frac{4}{7}:1\frac{1}{35}=\frac{18}{7}:\frac{36}{35}=\frac{18}{7}\cdot\frac{35}{36}=\frac{5}{2}=2\frac{1}{2}\).

Ответ: 1) \(7\frac{5}{7}\); 2) \(44\); 3) \(14\frac{1}{2}\); 4) \(\frac{7}{45}\); 5) \(\frac{3}{32}\); 6) \(1\frac{1}{5}\); 7) \(\frac{8}{9}\); 8) \(2\frac{1}{2}\).
