Question

Commutative property x=-2/3,y=-5/6

Answer 1

$\frac{ - 2}{3} + \frac{ - 5}{6} \\ = > \frac{ - 2}{3} \times \frac{2}{2} + \frac{ - 5}{6} \\ = > \frac{ - 4}{6} + \frac{ - 5}{6} \\ = > \frac{ - 9}{6}$
hope this will help u....

Answer 2

x+y=y+x
-2/3+(-5/6)=-5/6+(-2/3)
-4-5/6=-5-4/6
-9/6=-9/6...............................hence showed
