Решение:

1. \( \frac{5}{12} \cdot 4 = \frac{5}{3} \)
2. \( \frac{3}{7} \cdot 49 = 21 \)
3. \( \frac{5}{8} : 25 = \frac{5}{8} \cdot \frac{1}{25} = \frac{1}{40} \)
4. \( \frac{3}{14} : 9 = \frac{3}{14} \cdot \frac{1}{9} = \frac{1}{42} \)
5. \( 5 : \frac{15}{19} = 5 \cdot \frac{19}{15} = \frac{19}{3} \)
6. \( 4 : \frac{16}{25} = 4 \cdot \frac{25}{16} = \frac{25}{4} \)
7. \( \frac{5}{11} : 5 = \frac{5}{11} \cdot \frac{1}{5} = \frac{1}{11} \)
8. \( \frac{12}{35} : 6 = \frac{12}{35} \cdot \frac{1}{6} = \frac{2}{35} \)
9. \( 10 : 3\frac{1}{3} = 10 : \frac{10}{3} = 10 \cdot \frac{3}{10} = 3 \)
10. \( 3\frac{1}{6} : \frac{19}{24} = \frac{19}{6} : \frac{19}{24} = \frac{19}{6} \cdot \frac{24}{19} = 4 \)
11. \( 3\frac{3}{7} \cdot 1\frac{1}{6} = \frac{24}{7} \cdot \frac{7}{6} = \frac{24}{6} = 4 \)
