Hey Mate!!!

..ur answer is...

$after \: putting \: values... \\ \frac{2}{3} + ( \frac{4}{5} + { \frac{ -5}{6} )} = (\frac{2}{3 } + \frac{4}{5} ) + \frac{ - 5}{6} \\ ..\\ \frac{2}{3} + \frac{28 - 25}{30} = \frac{10 + 12}{15} - \frac{5}{6} \\.. \\ \frac{20 + 3}{30} = \frac{44- 25}{30} \\ .. \\ \frac{23}{30} = \frac{19}{30} \\ .. \\ \green{lhs \: is \: not \: equal \: to \: rhs} \\ so \: they \: are\: not \: equal...$
