Question

The sum of two rational numbers is −4. If one of them is $\frac{-11}{6}$, find the other.

Answer 1

$$\begin{gathered} \begin{array}{l}\mathrm{Let}\mathrm{the}\mathrm{required}\mathrm{number}\mathrm{be}x.\\ x+\left(\frac{-11}{6}\right)=-4\\ =>x=(-\text{4})-\left(\frac{-11}{6}\right)\\ \begin{array}{l}=-4+\frac{11}{6}\\ =\frac{-24+11}{6}\\ =\frac{-13}{6}\end{array}\end{array} \\ \mathrm{Hence},\mathrm{the}\mathrm{other}\mathrm{number}\mathrm{is}\frac{-13}{6}. \end{gathered}$$
