Answer 1

Answer:

The Solution for Your Question Is $\frac{-1}{36}$

Step-by-step explanation:

$\frac{7}{-9}+\frac{-3}{-4}$

= $\frac{-7}{9} +\frac{3}{4}$     [ Canceling the - as if we divide the - by - we get +]

= $\frac{-28}{36}+\frac{27}{36}$    [ Taking the LCM as 36 ]

= $\frac{-28+27}{36}$

= $\frac{-1}{36}$
