$(\frac{3}{5})\div (\frac{ - 2}{7}) + (\frac{ - 4}{7}) \times ( \frac{14}{20})$

$( \frac{3}{5} ) \times ( \frac{7}{ - 2} ) + ( \frac{ - 4}{7} ) \times ( \frac{14}{20} )$

$( \frac{21}{ - 10} ) + ( \frac{ - 1 \times 2}{1 \times 5} )$

$( \frac{ - 21}{10} ) + ( \frac{ - 2}{5} )$

$\frac{ - 21}{10} + ( \frac{ - 2 \times 2}{5 \times 2} )$

$\frac{ - 21 + ( - 4)}{10}$

$= \frac{ - 21 - 4}{10}$

$= \frac{ - 25}{10}$

$= \frac{ - 5}{2}$
