Answer 2

Hope u like my process
=====================
$\frac{5}{7} + \frac{1}{3} + \frac{8}{9} + \frac{1}{14} \\ = (\frac{1}{3} + \frac{8}{9} ) + ( \frac{5}{7} + \frac{1}{14} ) \\ = ( \frac{3 + 8}{9} ) + ( \frac{10 + 1}{14} ) \\ = \frac{11}{9} + \frac{11}{14} \\ = 11( \frac{1}{9} + \frac{1}{14} ) \\ = 11( \frac{14 + 9}{126} ) \\ = 11 \times \frac{23}{126} \: \: or \: \: \frac{253}{126}$
