Answer 2

Step-by-step explanation:

$\frac{2}{5} \times ( \frac{ - 7}{3} ) - \frac{1}{6} \times \frac{3}{2} + \frac{1}{14} \times \frac{2}{5} \\ = \frac{2}{5} \times \frac{ - 7}{3} - \frac{1}{2} \times \frac{1}{2} + \frac{1}{7} \times \frac{1}{5} \\ = \frac{ - 14}{15} - \frac{1}{4} + \frac{1}{35} \\ = \frac{ - 392 - 105 + 12}{420} \\ = \frac{485}{420} \\ = \frac{97}{84}$
