Answer 1

Ответ:

$(1 \frac{1}{9} - 5 \frac{1}{3} ) \div ( - \frac{1}{5} + 2.1) \\ (1 \frac{1}{9} - 5 \frac{3}{9} ) \div ( - \frac{2}{10} + 2 \frac{1}{10} ) \\ - 4 \frac{2}{9} \div 1 \frac{9}{10} = - \frac{38}{9} \div \frac{19}{10} \\ - \frac{38 \times 10}{9 \times 19 } = - \frac{20}{9} = - 2 \frac{2}{9}$
