Answer 2

$\bold{(x \div y) {}^{ - 1} = {x}^{ - 1} \div {y}^{ - 1} }$

$\bold{x = \frac{ - 7}{12} ,y = \frac{5}{9}}$

$\bold{ (\frac{ - 7}{12} \div \frac{5}{9} ) {}^{ - 1} = \frac{ - 7}{12} {}^{ - 1} \div \frac{5}{9} {}^{ - 1} }$

$\bold{ \small{ (\frac{ - 7}{12} \times \frac{9}{5}) = \frac{ - 21}{20}^{ - 1} = \frac{ - 7}{12} {}^{ - 1} \times \frac{9}{5} {}^{ - 1} }}$

$\small \bold{ \frac{ - 21}{20} {}^{ - 1} = - 420 = -84 \times 45 = - 3780}$

$\bold{- 420 \ne - 3780}$

$\bold{Here, \: LHS \ne \: RHS}$

$\bold{So,(x \div y) {}^{ - 1} = {x}^{ - 1} \div {y}^{ - 1} }$
