\large\bold{{Solve}}

\Rightarrow \bold{{ \frac{2}{5}  \times ( \frac{ - 3}{7}  -   \frac{ - 1}{6} ) \times  \frac{3}{8}  +  \frac{1}{14}  \times  \frac{2}{5} }}

 

\large\bold\color{yellow}{{{\: \:\: \:\:\:\:\: \:\:\: \: \: \: \:\:\: \: \:\: Solution}}}

 

\Rightarrow\bold{{ \frac{2}{5}  \times ( \frac{ - 3}{7}  -   \frac{ - 1}{6} ) \times  \frac{3}{8}  +  \frac{1}{14}  \times  \frac{2}{5} }}

 

\Rightarrow\bold{{LCM\:of\:7\:and\:6\:is\:42}}

 

\Rightarrow\bold{{\frac{3}{7}\times\frac{6}{6}=\frac{18}{42}}}

 

\Rightarrow\bold{{\frac{-1}{6}\times\frac{7}{7}=\frac{-7}{42}}}

 

\Rightarrow\bold{{\frac{2}{5}  \times \frac{18-(-7)}{42} \times  \frac{3}{8}  +  \frac{1}{14}  \times  \frac{2}{5}}}

 

\Rightarrow\bold{{\frac{2}{5}  \times \frac{18+7}{42} \times  \frac{3}{8}  +  \frac{1}{14}  \times  \frac{2}{5}}}

 

\Rightarrow\bold{{\frac{2}{5}  \times \frac{25}{42} \times  \frac{3}{8}  +  \frac{1}{14}  \times  \frac{2}{5}}}

 

\Rightarrow\bold{{\frac{50}{210}  \times  \frac{3}{8}  +  \frac{2}{70}}}

 

\Rightarrow\bold{{\frac{150}{1680} +  \frac{2}{70}}}

 

\Rightarrow\bold{{LCM\:of\:1680\:and\:70\:is\:1680}}

 

\Rightarrow\bold{{\frac{150}{1680}\times\frac{1}{1}=\frac{150}{168}}}

 

\Rightarrow\bold{{\frac{2}{70}\times\frac{24}{24}=\frac{48}{1680}}}

 

\Rightarrow\bold{{\frac{150+2}{1680}}}

 

\Rightarrow\bold{{\frac{152}{1680}}}

 

\Rightarrow\bold{{\frac{19}{210}}}
