Answer 1

Solution :

${\small{\tt{ \bigg\lbrace \dfrac{2}{3} - \bigg( \dfrac{-4}{5} \bigg) \bigg\rbrace - \dfrac{1}{2} = \dfrac{2}{3} - \bigg\lbrace \bigg( \dfrac{-4}{5} \bigg) - \dfrac{1}{2} \bigg\rbrace }}}$

${\implies{\small{\tt{ \bigg\lbrace \dfrac{2}{3} + \dfrac{4}{5} \bigg\rbrace - \dfrac{1}{2} = \dfrac{2}{3} - \bigg\lbrace \bigg( \dfrac{-4}{5} \bigg) - \dfrac{1}{2} \bigg\rbrace }}}}$

${\implies{\small{\tt{ \bigg\lbrace \dfrac{10+12}{15} \bigg\rbrace - \dfrac{1}{2} = \dfrac{2}{3} - \bigg\lbrace \dfrac{-8 -5}{10} \bigg\rbrace }}}}$

${\implies{\small{\tt{ \bigg\lbrace \dfrac{22}{15} \bigg\rbrace - \dfrac{1}{2} = \dfrac{2}{3} - \bigg\lbrace \dfrac{-13}{10} \bigg\rbrace }}}}$

${\implies{\small{\tt{ \dfrac{22}{15} - \dfrac{1}{2} = \dfrac{2}{3} + \dfrac{13}{10} }}}}$

${\implies{\small{\tt{ \dfrac{44-15}{30} = \dfrac{20 + 39}{30}}}}}$

${\implies{\small{\tt{ \dfrac{29}{30} \ne \dfrac{59}{30}}}}}$

No, ${\small{\tt{ \bigg\lbrace \dfrac{2}{3} - \bigg( \dfrac{-4}{5} \bigg) \bigg\rbrace - \dfrac{1}{2} \ne \dfrac{2}{3} - \bigg\lbrace \bigg( \dfrac{-4}{5} \bigg) - \dfrac{1}{2} \bigg\rbrace }}}$
