Answer 1

Respuesta:

$\frac{5}{3} + \frac{2}{3} = \frac{7}{3} \\ \frac{9}{6} + \frac{5}{6} = \frac{14}{6} = \frac{7}{3} \\ \frac{7}{5} - \frac{4}{5} = \frac{3}{5} \\ \frac{4}{10} + \frac{1}{5} = \frac{4 + (2 \times 1)}{10} \\ \frac{4 + 2}{10} = \frac{6}{10} = \frac{3}{5} \\ \\ \frac{5}{2} + \frac{3}{4} = \frac{(5 \times 2) + 3}{4} \\ = \frac{13}{4} \\ \frac{2}{3} + \frac{1}{6} = \frac{2(2) + 1}{6} = \\ \frac{5}{6}$
