hint :- the LCM of 22,11,33 =66​

Answer 1

$= \frac{ - 9}{22} + \frac{7}{11} + \frac{ - 8}{33} \\ \\ = \frac{ - 27 + 42 - 16}{66} \\ \\ = \frac{ - 1}{66}$

Answer 2

$\frac{ - 9}{22} \times 66 \\ = - 27$

$\frac{ - 8}{33} \times 66 \\ = - 16$

$\frac{7}{11}\times66 \\ = 42$

$\frac{ - 27 + 42 + (- 16)}{66} \\ ans = -1$
