Ответ: -26,1

$(7 \frac{3}{5} \times ( - 2.5) - 4 \frac{3}{20} \times ( - 10)) \times (2 - 3 \frac{4}{25} ) = (\frac{38}{5} \times ( - \frac{25}{10} ) - \frac{83}{20} \times ( - 10)) \times (2 - 3.16) = ( - \frac{95}{5} - ( - \frac{83}{2} )) \times ( - 1.16) = ( - 19 + 41.5) \times ( - 1.16) = 22.5 \times ( - 1.16) = - 26.1$
