Answer 1

Respuesta:

Explicación paso a paso:

$\frac{3}{4} + \frac{4}{6} = \frac{3}{4} + \frac{2}{3} = \frac{9+8}{12} = \frac{17}{12} \\\\\frac{5}{7} - \frac{2}{4} = \frac{5}{7} - \frac{1}{2} = \frac{10-7}{14} = \frac{3}{14} \\\\\frac{3}{5} + \frac{2}{6} = \frac{3}{5} + \frac{1}{3} = \frac{9+5}{15} = \frac{14}{15} \\\\\\\\frac{6}{9} - \frac{2}{5} = \frac{2}{3} - \frac{2}{5} = \frac{10-6}{15} = \frac{4}{15} \\\\\frac{2}{3} + \frac{7}{8} = \frac{16+21}{24} = \frac{37}{24}\\\\\frac{5}{6} - \frac{4}{7} = \frac{35-24}{42} = \frac{11}{42}$
