Пошаговое объяснение:

$\displaystyle \large \boldsymbol{} \frac{28a^2}{27x^3} \cdot \frac{-63x^4}{150a} : \frac{49a^2}{25x^2} =\frac{4\cdot 7a^2\!\!\!\!\!\diagup}{3\cdot 9\!\!\!\!\diagup x^3} \cdot \frac{9\!\!\!\!\diagup\cdot-7x^4}{25\!\!\!\!\diagup\cdot6a }\cdot \frac{25\!\!\!\!\diagup x^2}{49a^2\!\!\!\!\!\diagup} = \\\\\\\frac{-4\cdot 49\!\!\!\!\diagup x^6}{6\cdot 3\cdot 49\!\!\!\!\diagup x^3\cdot a} =\frac{-4x^3\cd}{18a} =\boxed{-\frac{2x^3}{9a}}$
