Let's Take An Example , x = 7/11 & y = -6/5

\begin{gathered}x - y = \frac{7}{11} - ( - \frac{6}{5} ) \\ = > \frac{7}{11} + \frac{6}{5} \\ \\ = > \frac{35 + 66}{55} \\ \\ = > \frac{101}{55} \\ \\ y - x \\ \\ = > - \frac{6}{5} - \frac{7}{11} \\ \\ = > \frac{ - 66 - 35}{55} \\ \\ = > \frac{ - 101}{55} \end{gathered}
