Answer 1

Answer:

Just multiply numerator and denominator with (-) sign,

a) $\frac{-14}{17}$ = $\frac{- (-14)}{-17}$ = $\frac{14}{-17}$

b) At both numerator and denominator  '-' sign is present, they will be cancelled out  

i.e. $\frac{-9}{-13}$ = $\frac{9}{13}$

c) It's similar to that of first one,

$\frac{-12}{31}$ = $\frac{- (-12)}{-31}$ = $\frac{12}{-31}$

d) Again, both numerator and denominator  '-' sign is present, they will be cancelled out,

$\frac{-67}{-112}$ = $\frac{67}{112}$

It's easy-peasy.
