Answer 2

Respuesta:

$\frac{9}{7} - \frac{2}{7} = \frac{63 - 14}{49} = \frac{49}{49} = \frac{7}{7}$

$\frac{5}{6} - \frac{5}{12} = \frac{60 - 30}{72} = \frac{30}{72} = \frac{15}{36} = \frac{5}{12}$

$\frac{3}{5} + \frac{2}{8} = \frac{24 + 10}{40} = \frac{34}{40} = \frac{17}{20}$

$\frac{5}{4} + \frac{1}{6} = \frac{30 + 4}{24} = \frac{34}{24} = \frac{17}{12}$
