$( - \frac{11}{18} + ( - 2 \frac{2}{9} ) \times ( - 0.2)) {}^{ {}^{3} } \times ( - 1.2) \\ \\ = ( - \frac{11}{18} + ( - \frac{20}{9} ) \times ( - \frac{1}{5} )) {}^{ {}^{3} } \times ( - 1.2) \\ \\ = ( - \frac{11}{18} + \frac{4}{9} ) {}^{ {}^{3} } \times ( - 1.2) \\ \\ = ( - \frac{1}{6} ) {}^{ {}^{3} } \times ( - 1.2) \\ \\ = - ( \frac{1}{6} ) {}^{ {}^{3} } \times ( - 1.2) \\ \\ = \frac{1}{216} \times \frac{6}{5} \\ \\ = \frac{1}{36} \times \frac{1}{5} \\ \\ = \frac{1}{180}$
