Answer 2

Answer:

$\bold{ \frac{157}{280} }$

Step-by-step explanation:

$- \frac{2}{5} \times ( \frac{ - 3}{7} ) - \frac{ 1}{14} - \frac{3}{5} \times \frac{3}{7} \div ( - \frac{8}{15} ) \\ \frac{ 6}{35} - \frac{1}{14} - \frac{3}{5} \times \frac{3}{7} \times ( - \frac{15}{8} ) \\ \frac{6}{35} - \frac{1}{14} + \frac{135}{280} \\ \frac{6}{35} - \frac{1}{14} + \frac{27}{56} \\ \frac{6}{5\times 7} - \frac{1}{2 \times 7} + \frac{27}{2 \times 2 \times 2 \times 7} \\ \frac{42 - 20 +135 }{280} \\ \frac{157}{280}$
