Answer 2

$\huge\fcolorbox{pink}{yellow}{Solution :- }</p><p>$

$\frac { 5 } { 22 } + \frac { 3 } { 7 } + [ \frac { - 8 } { 21 } ] + [ \frac { - 6 } { 11 } ]$

$\frac{35}{154}+\frac{66}{154}+\frac{-8}{21}+\frac{-6}{11}$

$\frac{35+66}{154}+\frac{-8}{21}+\frac{-6}{11}$

$\frac{101}{154}+\frac{-8}{21}+\frac{-6}{11}$

$\frac{101}{154}-\frac{8}{21}+\frac{-6}{11}$

$\frac{303}{462}-\frac{176}{462}+\frac{-6}{11}$

$\frac{303-176}{462}+\frac{-6}{11}$

$\frac{127}{462}+\frac{-6}{11}$

$\frac{127}{462}-\frac{6}{11}$

$\frac{127}{462}-\frac{252}{462}$

$\frac{127-252}{462}$

$-\frac{125}{462}$
