Answer 2

(6) Let the rational number be ${x}$

Now, According to Question

${\dfrac{-7}{8}+x=\dfrac{5}{9}}$

-» ${x = \dfrac{5}{9}+\dfrac{7}{8}}$

-» ${x = \dfrac{40+63}{72}}$

-» ${x = \dfrac{103}{72}}$

(7) Let the rational number be ${x}$

In the same way,

${\dfrac{-5}{9}+x=\dfrac{-2}{3}}$

-» ${x = - \dfrac{2}{3}+\dfrac{5}{9}}$

-» ${x = -\dfrac{6}{9}+\dfrac{5}{9}}$

-» ${x = \dfrac{-6+5}{9}}$

-» ${x = \dfrac{-1}{9}}$
