Answer:
[tex] - \frac{6437}{1656} [/tex]
Step-by-step explanation:
[tex](5 + \frac{1}{5} - \frac{2}{9} ) - (2 - \frac{1}{23} - 2 \frac{3}{35} + \frac{5}{6} ) - (8 + ( \frac{2}{7} - \frac{1}{8} )[/tex]
[tex] = \frac{224}{45} - (2 - \frac{1}{23} - \frac{73}{35} + \frac{5}{6} ) - \frac{457}{56} [/tex]
[tex] = \frac{224}{45} - \frac{3401}{4830} - \frac{457}{56} [/tex]
[tex] = - \frac{6437}{1656} [/tex]
