Solution

Given, $\frac{13}{11} \times \frac{- 14}{5} + \frac{13}{11} \times \frac{- 7}{5} + \frac{- 13}{11} \times \frac{34}{5} = \frac{13 \times (- 14)}{11 \times 5} + \frac{13 \times (- 7)}{11 \times 5} + \frac{(- 13) \times 34}{11 \times 5} = \frac{- 182}{55} + \frac{(- 91)}{55} + \frac{(- 442)}{55} = \frac{- 182 - 91 - 442}{55} = \frac{- 715}{55} = - 13$
