Answer 2

Step-by-step explanation:

$add: \frac{-5}{9} , \frac{-4}{3} , \frac{7}{12}$

$lcm \: of \: 9 , 3 , 12 = 36$

$\frac{ - 5}{9} , \frac{-4}{3} , \frac{7}{12} = \frac{-5}{9} \times \frac{4}{4} + \frac{-4}{3} \times \frac{12}{12} + \frac{7}{12} \times \frac{3}{3}$

$= \frac{-20}{36} + \frac{-48}{36} + \frac{21}{36}$

$= \frac{ - 20 - 48 + 21 }{36} = \frac{ - 47}{36}$
