Задание № 12. Выполните деление: 1) 8 1/6 : 3 1/9; 2) 1 1/50 : 3 6/25; 3) 1 7/8 : 4 1/6; 4) 5 5/14 : 2 1/7; 5) 4 8/15 : 1 9/25; 6) 2 1/3 : 1 5/9.

1. \(8\frac16:3\frac19=\frac{49}{6}:\frac{28}{9}=\frac{21}{8}=2\frac58\).
2. \(1\frac1{50}:3\frac6{25}=\frac{51}{50}:\frac{81}{25}=\frac{17}{54}\).
3. \(1\frac78:4\frac16=\frac{15}{8}:\frac{25}{6}=\frac9{20}\).
4. \(5\frac5{14}:2\frac17=\frac{75}{14}:\frac{15}{7}=\frac52=2\frac12\).
5. \(4\frac8{15}:1\frac9{25}=\frac{68}{15}:\frac{34}{25}=\frac{10}{3}=3\frac13\).
6. \(2\frac13:1\frac59=\frac73:\frac{14}{9}=\frac32=1\frac12\).

Ответ: 1) 2 5/8; 2) 17/54; 3) 9/20; 4) 2 1/2; 5) 3 1/3; 6) 1 1/2.
