Answer 2

$\red{\bigstar \large\underline{\boxed{\bf\pink{Answer:-}}}}$

$\sf \red{ \frac{1}{2} \times \frac{ - 3}{5} + \frac{7}{10} }$

$\sf \green{ \mapsto \frac{1 \times - 3}{3 \times 7} + \frac{7}{10} }$

$\sf \blue{ \mapsto \frac{ - 3}{21} + \frac{7}{10} }$

$\sf \purple{ \mapsto\frac{ - 3 \times 7}{21 \times 10} }$

$\sf \color{brown} \mapsto\frac{ - 21}{210}$

$\sf \color{skyblue}\mapsto\frac{\cancel{- 21}}{\cancel{210}}$

$\sf\gray{\mapsto\frac{ - 1}{10} }$

$\pink{ \underline{ \boxed{ \sf{ \therefore \: The \: answer \: = \frac{ - 1}{10} }}}}$
