Respuesta:

$\frac{8}{10} + \frac{1}{12} = \frac{53}{60}$

$\frac{6}{10} + \frac{3}{6} = \frac{11}{10}$

$\frac{5}{6} - \frac{2}{4} = \frac{1}{3}$

$\frac{4}{7} - \frac{2}{3} = \frac { 2}{21}$

Answer 2

$\frac{8}{10} + \frac{1}{12} = \frac{96 + 10 }{120} = \frac{106}{120} = \frac{53}{60} \\ \\ \\ \frac{6}{10} + \frac{3}{6} = \frac{36 + 30}{60} = \frac{66}{60} = \frac{33}{30} \\ \\ \\ \frac{5}{6} - \frac{2}{4} = \frac{20 - 12}{20} = \frac{8}{20} = \frac{4}{10} \\ \\ \\ \frac{4}{7} - \frac{2}{3} = \frac{12 - 14}{21} = \frac{2}{21}$
