Answer 1

Respuesta:

$\frac{3}{5} + \frac{1}{3} = \frac{9 + 5}{15} = \frac{14}{15}$

$\frac{2}{5} + \frac{3}{4} = \frac{8 + 15}{20} = \frac{23}{20}$

$\frac{3}{7} + \frac{5}{21} = \frac{63 + 35}{147} = \frac{98}{147} = \frac{2}{3}$

$\frac{7}{9} + \frac{1}{2} = \frac{14 + 9}{18} = \frac{23}{18}$

$\frac{2}{4} + \frac{3}{8} = \frac{12 + 16}{32} = \frac{28}{32} = \frac{7}{8}$

$\frac{5}{6} + \frac{1}{2} = \frac{10 + 6}{12} = \frac{16}{12} = \frac{4}{3}$
