Question

State whether the statement are true or false :-
(2/7-4/9)-1/8=2/7-(4/9-1/8)

Answer 1

$\textit{\large{\pink{\underline{\underline{Step by step Explanation:-}}}}}$

$\mathrm{(\frac{2}{7}-\frac{4}{9})-\frac{1}{8}=\frac{2}{7}-(\frac{4}{9}-\frac{1}{8})}$

$\mathrm{\implies{(\frac{18-28}{63})-\frac{1}{8}=\frac{2}{7}-(\frac{32-9}{72})}}$

$\mathrm{\implies{\frac{-10}{63}-\frac{1}{8}=\frac{2}{7}-frac{23}{72}}}$

$\mathrm{\implies{\frac{-80-63}{504}=\frac{144-161}{504}}}$

$\mathrm{\implies{\frac{-143}{504}=\frac{-17}{504}}}$

$\mathit{\underline{Hence,,}}$

$\mathrm{\boxed{\red{LHS\ne RHS}}}$

So,, it is False...
