Answer 1

Respuesta:

$\frac{2}{5} +\frac{7}{10} =\frac{4}{10} +\frac{7}{10} =\frac{11}{10}$

$-\frac{3}{4} +\frac{12}{7} =-\frac{21}{28} +\frac{48}{28} =\frac{27}{28}$

$\frac{2}{11} +5\frac{1}{3}-4 =\frac{2}{11} +\frac{16}{3} -4=\frac{6}{33}+\frac{176}{33}-\frac{132}{33} =\frac{50}{33}$

$\frac{4}{3} +\frac{1}{6} =\frac{8}{6} +\frac{1}{6} =\frac{9}{6}$
