Answer 1

Respuesta:

$\frac{1}{2} + \frac{5}{4} = \frac{2}{4} + \frac{5}{4} = \frac{7}{4}$

$\frac{9}{3} + \frac{3}{7} = \frac{63}{21} + \frac{9}{21} = \frac{72}{21 } = \frac{24}{7}$

$\frac{2}{8} + \frac{2}{7} = \frac{1}{4} + \frac{2}{7} = \frac{7}{28} + \frac{8}{28} = \frac{15}{28}$

$\frac{4}{6} + \frac{7}{7} = \frac{2}{3} + \frac{7}{7} = \frac{14}{21} + \frac{21}{21} = \frac{35}{21} = \frac{5}{3}$

$\frac{9}{3} + \frac{2}{8} = 3 + \frac{1}{4} = \frac{12}{4} + \frac{1}{4} = \frac{13}{4}$

$\frac{2}{5} + \frac{7}{6} = \frac{12}{30} + \frac{35}{30} = \frac{47}{30}$
