Question 81 (i)

Simplify: $\frac{13}{11}\times \frac{-14}{5}+\frac{13}{11}\times \frac{-7}{5}+\frac{-13}{11}\times \frac{34}{5}$

Answer 1

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