Answer 1

Respuesta:

$\frac{5}{6} - \frac{8}{9} = \frac{45 - 48}{54} = - \frac{3}{54} = \ - \frac{ 1 }{18}$

$3 \frac{4}{7} - 4 \frac{1}{5} = \frac{25}{7} - \frac{21}{5} = \frac{125 - 147}{35} = - \frac{ 22}{35}$

$\frac{3}{15} + \frac{5}{5} - \frac{7}{10} = \frac{6 + 30 - 21}{30} = \frac{36 - 21}{30} = \frac{15}{30} = \frac{1}{2}$
