Answer 2

ANSWER✔

$\large\underline\bold{GIVEN,}$

$\sf\dashrightarrow \left( \dfrac{\dfrac{13}{15} + \big(\dfrac{-12}{7}\big)}{ \dfrac{(-31)}{7} \times \dfrac{1}{(-2)}} \right)$

$\large\underline\bold{SOLUTION,}$

$\sf\implies \left( \dfrac{\dfrac{13}{15} + \big(\dfrac{-12}{7}\big)}{ \dfrac{(-31)}{7} \times \dfrac{1}{(-2)}} \right)$

$\sf\implies \left( \dfrac{\dfrac{(13 \times 7)+(-12) \times 15}{7 \times 5}}{\dfrac{(\cancel{-} \:31) \times 1}{7 \times (\cancel{-}\:2)}} \right)$

$\sf\implies \left( \dfrac{\dfrac{91+(-60)}{35}}{\dfrac{31}{14}} \right)$

$\sf\implies \left(\dfrac{\dfrac{31}{35}}{\dfrac{31}{14}}\right)$

$\sf\implies \dfrac{31}{35} \times \dfrac{14}{31}$

$\sf\implies \dfrac{\cancel{31}}{35} \times \dfrac{14}{\cancel{31}}$

$\sf\implies \dfrac{14}{35}$

$\sf\implies \cancel \dfrac{14}{35}$

$\large{\boxed{\bf{ \star\:\:\implies \dfrac{2}{5}\:\: \star}}}$
