Answer 2

Answer:

Given Expression is $\frac{3}{7}+(\frac{-6}{11})+(\frac{-8}{21})+\frac{5}{22}$

We have to simplify it

$\frac{3}{7}+(\frac{-6}{11})+(\frac{-8}{21})+\frac{5}{22}$

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

$\implies\frac{33-42}{77}+\frac{-176+105}{462}$

$\implies\frac{-9}{77}+\frac{-71}{462}$

$\implies\frac{-54-71}{462}$

$\implies\frac{-125}{462}$
