Answered by SHREYADAS23

both are positive dude !!!!
-12/-17 = 12/17
-19/-21= 19/21

riya9898: but in my book it is written that first one is negative and the second part is positive

SHREYADAS23: ok

riya9898: so can you please tell me that what is the answer and how

Answered by SaikiaPriyanka1

Both of them are positive as -12/-17 minus - minus of both of the sums will get cancelled.
So,
-12/-17 = 12/17
-19/-21 = 19/21
