Answer 1

Respuesta:

$\frac{8}{9} + \frac{1}{2} = \frac{16}{18} + \frac{9}{18} = \frac{25}{18}$

$\frac{3}{5} + \frac{1}{7} = \frac{21}{35} + \frac{5}{35} = \frac{26}{35}$

$\frac{3}{4} - \frac{2}{5} = \frac{15}{20} - \frac{8}{20} = \frac{7}{20}$

$\frac{2}{7 } - \frac{1}{6} = \frac{12}{42} - \frac{7}{42} = \frac{5}{42}$
