Answer 1

⚘Required Answer :

$\frac{629}{1680}$

⚘Step-by-Step Explanation :

$\frac{3}{7} + ( - \frac{1}{6}) + ( - \frac{1}{8} ) + \frac{5}{22}$

$\frac{3}{7} - \frac{1}{6} - \frac{1}{8} + \frac{5}{22}$

$\frac{18 - 7}{42} - \frac{11 + 20}{88}$

$\frac{11}{42} + \frac{9}{80}$

$\frac{440 + 180}{1680}$

$\frac{629}{1680}$
