Answer 2

Answer:

Your Question is -7/10 + 13/-15 + 27/20

First Take LCM

We can't take the LCM of a negative term so , we should put that -tive sign to numerator

so it will be -7/10 + (-13/15) + 27/20

So the LCM is 60

-42-52+81

-----------------

60

-94+81

-----------

60

so the ans is -13/60
