Answer 2

Step-by-step explanation:

let's take that LHS=RHS

then,

        (X-Y)-Z = X-(Y-Z)

$=> [(\frac{-2}{3} )-(\frac{-4}{5} )]- (\frac{1}{2} ) =(\frac{-2}{3} ) - [(\frac{-4}{5} )-(\frac{1}{2} )]\\=> [(\frac{-10+12}{15} )]- (\frac{1}{2} ) =(\frac{-2}{3} ) - [(\frac{-8-5}{10}] \\=> (\frac{2}{15} )- (\frac{1}{2} ) =(\frac{-2}{3} ) - [(\frac{-13}{10}] \\=> (\frac{4-15}{30} ) =(\frac{-20+39}{30})\\=> \frac{11}{30}\neq \frac{19}{30}$
