Answer 1

Respuesta:

$\frac{6}{7} - \frac{3}{4} = \frac{24}{28} - \frac{21}{28} = \frac{3}{28} \\ \\ \frac{4}{5} + \frac{4}{8} = \frac{32}{40} + \frac{20}{40} = \frac{52}{40} \\ \\ \\ \frac{8}{12} + \frac{2}{4} = \frac{32}{48} + \frac{24}{48} = \frac{56}{48} \\ \\ \\ \frac{7}{9} - \frac{2}{5} = \frac{35}{45} - \frac{18}{45} = \frac{17}{45}$
