Answer 1

Hey
__________________________________________

I) -7/9+3/4

First take the L. C. M of 9 and 4
And the L. C. M of 9 and 4 is 36

= -7×4/9×4 + 3×9/4×9

= -28 + 27/36

= -1/36

II) -3/-11 + 5/9

Take the L. C. M of 11 and 9
And the L. C. M of 11 and 9 is 99

= -3×9/-11×9 + 5×11/9×11

= -27 + 55/99

= 28/99

Answer 2

HEYA!!
---------

[ 1 ]. -7 / 9. + 3/4


Taking LCM,

= -28 + 27 /36

= -1/36


[ 2 ]. -3/-11 + 5/9

The -ve sign cancels out ,


Taking LCM,


27 + 55 /99

= 8 2 / 99
