Answer 2

Answer:

$\frac{2}{5}$

Step-by-step explanation:

Since, the sum 13/5 and-12/7,

$=\frac{13}{5}+(-\frac{12}{7})$

$=\frac{91-60}{35}$

$=\frac{31}{35}$

Also, the product of-31/7 and 1/-2,

$=\frac{-31}{7}\times -\frac{1}{2}$

$=\frac{31}{14}$

Thus,

$\frac{31}{35}\div \frac{31}{14}=\frac{31}{35}\times \frac{14}{31}=\frac{14}{35}=\frac{2}{5}$

Which is the required answer.
