Question

Simplify (-8/5 *3/4) + (7/8* -16/25)

Answer 1

Dear Student,

$$\begin{gathered} \frac{-8}{5}\times \frac{3}{4}+\frac{7}{8}\times \frac{-16}{25} \\ \Rightarrow \frac{{\displaystyle -2}}{{\displaystyle 5}}\times \frac{{\displaystyle 3}}{{\displaystyle 1}}+\frac{{\displaystyle 7}}{{\displaystyle 1}}\times \frac{{\displaystyle -2}}{{\displaystyle 25}} \\ \Rightarrow \frac{{\displaystyle -6}}{{\displaystyle 5}}+\frac{{\displaystyle -14}}{{\displaystyle 25}} \\ \Rightarrow \frac{{\displaystyle -6}}{{\displaystyle 5}}-\frac{{\displaystyle 14}}{{\displaystyle 25}} \\ \Rightarrow \frac{{\displaystyle -6\times 5-14}}{{\displaystyle 25}} \\ \Rightarrow \frac{-30-14}{25} \\ \Rightarrow \frac{-44}{25} \end{gathered}$$
