Answer 2

Answer:

$\frac{2}{5} \times \frac{ - 3}{7} - \frac{1}{6} \times \frac{3}{2} + \frac{1}{14} \times \frac{2}{5} \\ = (\frac{2}{5} \times \frac{ - 3}{7}) - (\frac{1}{6} \times \frac{3}{2} ) + ( \frac{1}{14} \times \frac{2}{5}) \\ = (\frac{2}{5} \times \frac{ - 3}{7}) - (\frac{1}{ _{2 \: \: \: } \cancel 6} \times \frac{ \cancel 3 _{ \: \: \: 1}}{2} ) + ( \frac{1}{_{7 \: \: \: } \cancel{ 14}} \times \frac{ \cancel 2 _{ \: \: \: 1} }{5}) \\ = \frac{ - 6}{35} - \frac{1}{4} + \frac{1}{35} \\ = \frac{ - 24 - 35 + 4}{140} \\ = \frac{ \cancel{ - 55} _{ \: \: \: - 11} }{ \cancel{ 140} _{ \: \: \: 28} } \\ \boxed{ \boxed{ = \underline{ \underline{ \large \frac{ - 11}{28} }}}}$
