1. a) \(57: (-19) = -3\)
2. б) \(-123 : 41 = -3\)
3. в) \(-147: (-7) = 21\)
4. г) \(14.31 : (-2.7) = -5.3\)
5. д) \(-86.2: (-0.1) = 862\)
6. е) \(-51.34: (-1.7) = 30.2\)
7. ж) \(-1 \frac{3}{8} : \frac{4}{11} = -\frac{11}{8} : \frac{4}{11} = -\frac{11}{8} \cdot \frac{11}{4} = -\frac{121}{32} = -3 \frac{25}{32}\)
8. з) \(\frac{4}{7} : (-1 \frac{2}{7}) = \frac{4}{7} : (-\frac{9}{7}) = \frac{4}{7} \cdot (-\frac{7}{9}) = -\frac{4}{9}\)
9. и) \(-1 \frac{1}{8} : (-1 \frac{1}{2}) = -\frac{9}{8} : (-\frac{3}{2}) = -\frac{9}{8} \cdot (-\frac{2}{3}) = \frac{3}{4}\)
10. к) \(-0.12 : (-1 \frac{4}{5}) = -\frac{12}{100} : (-\frac{9}{5}) = -\frac{3}{25} \cdot (-\frac{5}{9}) = \frac{1}{15}\)
11. л) \(0.1 : (-\frac{1}{12}) = \frac{1}{10} : (-\frac{1}{12}) = \frac{1}{10} \cdot (-12) = -\frac{6}{5} = -1 \frac{1}{5}\)
12. м) \(-\frac{4}{9} : 1.6 = -\frac{4}{9} : \frac{16}{10} = -\frac{4}{9} : \frac{8}{5} = -\frac{4}{9} \cdot \frac{5}{8} = -\frac{5}{18}\)
