Question

Prove that the communicative property does not hold true for 7/11 -6/5

Answer 1

Step-by-step explanation:$commutative \: property \: says \: in \: subtraction \\ \\ x - y \: not \: equal \: to \: y - x$Let's Take An Example , x = 7/11 & y = -6/5

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

Clearly , You Can See That x - y Not equal to y - x.
