Answer 2

ANSWER :

$a - b = \frac{2}{3} - \frac{1}{9} \\ \\ = \frac{6 - 1}{9} = \frac{5}{9} \\ \\ b - a = \frac{1}{9} - \frac{2}{3} \\ \\ = \frac{1 - 6}{9} = \frac{ - 5}{9} \\ \\ \frac{ - 5}{9} is \: not \: equal \: to \: \frac{5}{9} \\ \\ = > a - b \: is \: not \: equal \: to \: b - a$

∴ a - b ≠ b - a
