Answer 2

Answer:

$\sf -\dfrac{1}{36}$

Explanation:

$\rightarrow \sf -\dfrac{7}{9} -(-\dfrac{5}{12} )+\dfrac{1}{3}$

remove parenthesis

$\rightarrow \sf -\dfrac{7}{9} +\dfrac{5}{12} +\dfrac{1}{3}$

all the denominators has a common multiple of 108

$\rightarrow \sf -\dfrac{7(12)}{108} +\dfrac{5(9)}{108} +\dfrac{1(36)}{108}$

simplify

$\rightarrow \sf \dfrac{-84}{108} +\dfrac{45}{108} +\dfrac{36}{108}$

join the fractions

$\rightarrow \sf \dfrac{-84+45+36}{108}$

simplify

$\rightarrow \sf \dfrac{-3}{108}$

simplify

$\rightarrow \sf -\dfrac{1}{108}$
