Respuesta:

$\frac{7}{6} + \frac{2}{5} = \frac{35 + 12}{3 0 } = \frac{47}{30 } \\ \\ \ \\ \ \frac{1}{7} + \frac{1}{8} = \frac{8 + 7}{56} = \frac{15}{56} \\ \\ \\ \frac{7}{13} + \frac{5}{10} = \frac{14 + 13}{26} = \frac{27}{26} \\ \\ \\ \frac{7}{5} - \frac{1}{3} = \frac{21 - 5}{15} = \frac{16}{5} \\ \\ \\ \frac{8}{7} - \frac{9}{11} = \frac{88 - 63}{77} = \frac{25}{77} \\ \\ \\ \frac{11}{4} - \frac{1}{9} = \frac{99 - 4}{36} = \frac{95}{36}$
