Answer 2

Solution

$\:$

$\large \implies\rm \: \dfrac{1}{2} + \dfrac{ - 3}{4}$

$\:$

• Take L.C.M

$\:$

$\large \implies\rm \: \dfrac{2 - 3}{4}$

$\:$

• Sum ,

$\:$

$\large = \rm \: \dfrac{ - 1}{4}$

$\:$

• Product

$\:$

$\large \implies\rm \: \dfrac{1}{2} \times \dfrac{ - 3}{4}$

$\:$

$\large = \rm \: \dfrac{ - 3}{8}$

$\:$

• Division

$\:$

$\large \implies \rm \: \dfrac{ - 1}{4} \div \dfrac{ - 3}{8}$

$\:$

$\large \implies \rm \: \dfrac{ - 1}{4} \times \dfrac{ 8}{ - 3}$

$\:$

$\large \implies \rm \: \dfrac{ \cancel - \: 1}{ \cancel4} \times \dfrac{ \cancel8 \: \: 2}{ \cancel- \: 3}$

$\:$

$\large \boxed{ \therefore \rm \: \dfrac{ 2}{3} } \rm \: \: is \: answer$
