Respuesta:
[tex] \frac{6}{7} - \frac{2}{7} = \frac{4}{7} \\ \\ \frac{3}{4} - \frac{1}{4} = \frac{1}{2} \\ \\ \frac{6}{8} + \frac{3}{8} = \frac{9}{8} \\ \\ \frac{8}{7} - \frac{4}{7} = \frac{4}{7} \\ \\ \frac{4}{5} + \frac{2}{5} = \frac{6}{5} \\ \\ \frac{4}{5} - \frac{3}{5} = \frac{1}{5} \\ \\ \frac{6}{2} - \frac{4}{2} = 1 \\ \\ \frac{5}{9} + \frac{1}{9} = \frac{2}{3} [/tex]
