2) \[ \frac{6}{11} : (-\frac{11}{2}) = \frac{6}{11} \cdot (-\frac{2}{11}) = -\frac{12}{121} \] 2) \[ -1\frac{1}{6} : (-\frac{2}{3}) = -\frac{7}{6} : (-\frac{2}{3}) = -\frac{7}{6} \cdot (-\frac{3}{2}) = \frac{21}{12} = \frac{7}{4} = 1\frac{3}{4} \] r) \[ -0,18 : (-2\frac{2}{5}) = -0,18 : (-\frac{12}{5}) = -\frac{18}{100} : (-\frac{12}{5}) = -\frac{9}{50} \cdot (-\frac{5}{12}) = \frac{9 \cdot 5}{50 \cdot 12} = \frac{3 \cdot 1}{10 \cdot 4} = \frac{3}{40} \] 6) \[ -1\frac{2}{9} : 3 = -\frac{11}{9} : \frac{3}{1} = -\frac{11}{9} \cdot \frac{1}{3} = -\frac{11}{27} \]
