Answer 1

Explicación paso a paso:

$\frac{5}{8} - \frac{6}{7} + \frac{8}{4} = \frac{35 - 48 + 112}{56} = \frac{99}{56}$

$\frac{5}{4} + \frac{4}{6} + \frac{7}{9} = \frac{45 + 24 + 28}{36} = \frac{97}{36}$

$\frac{8}{2} - \frac{4}{5} - \frac{6}{2} = \frac{40 - 8 - 30}{10} = \frac{2}{10} = \frac{1}{5}$

$\frac{4}{5} + \frac{9}{12} - \frac{1}{6} = \frac{48 + 45 - 10}{60} = \frac{83}{60}$

$\frac{8}{5} - \frac{1}{6} + \frac{2}{8} = \frac{192 - 20 + 30}{120} = \frac{202}{120} = \frac{101}{60}$

$\frac{9}{12} - \frac{2}{8} - \frac{3}{7} = \frac{126 - 42 - 72}{168} = \frac{12}{168} = \frac{1}{14}$
