Answer 1

$\Rightarrow( \frac{ - 2}{5} + \frac{ - 4}{15} + \frac{1}{3} ) \div ( \frac{6}{7} - \frac{3}{5} )$

$\Rightarrow( \frac{ - 6}{15} + \frac{ - 4}{15} + \frac{5}{15}) \div ( \frac{30 - 21}{35} )$

$\Rightarrow \frac{ - 5}{15} \div \frac{9}{35}$

$\Rightarrow \frac{ - 5}{15} \times \frac{35}{9}$

$\Rightarrow \frac{ - 1}{3} \times \frac{35}{9}$

$\Rightarrow \frac{ - 35}{27}$
