Respuesta:

[tex] \frac{3}{5} + \frac{1}{3} = \frac{9 + 5}{15} = \frac{14}{15} [/tex]

[tex] \frac{2}{5} + \frac{3}{4} = \frac{8 + 15}{20} = \frac{23}{20} [/tex]

[tex] \frac{3}{7} + \frac{5}{21} = \frac{63 + 35}{147} = \frac{98}{147} = \frac{2}{3} [/tex]

[tex] \frac{7}{9} + \frac{1}{2} = \frac{14 + 9}{18} = \frac{23}{18} [/tex]

[tex] \frac{2}{4} + \frac{3}{8} = \frac{12 + 16}{32} = \frac{28}{32} = \frac{7}{8} [/tex]

[tex] \frac{5}{6} + \frac{1}{2} = \frac{10 + 6}{12} = \frac{16}{12} = \frac{4}{3} [/tex]
