Answer 2

The value of the expression is $-\frac{1014}{245}$.

Step-by-step explanation:

The expression is:

$(-13\div 5\times 12\div7)\times (-31\div7\times -1\div2)$

Simplify as follows:

$(-13\div 5\times 12\div7)\times (-31\div7\times -1\div2)=(\frac{-13}{5}\times \frac{12}{7})\times (\frac{-31}{7}\times \frac{-1}{2})$

                                                                $=(\frac{-156}{35})\times (\frac{13}{14})$

                                                                $=-\frac{1014}{245}$

Thus, the value of the expression is $-\frac{1014}{245}$.
