Answer:
\[\left[ \frac{7}{5}\times \left( \frac{-3}{12} \right) \right]+\left[ \frac{7}{5}\times \frac{5}{12} \right]=\frac{7}{5}\times \left\{ \left( \frac{-3}{12} \right)+\frac{5}{12} \right\}\] \[=\frac{7}{5}\times \left\{ \frac{-3+5}{12} \right\}\] \[=\frac{7}{5}\times \frac{2}{12}=\frac{7}{5}\times \frac{1}{6}=\frac{7}{30}\]
