Answer 1

Respuesta:

$\frac{5}{6} + \frac{1}{12} = \frac{10 + 1}{12} = \frac{11}{12} \\ \\ \frac{1}{7} + \frac{8}{21} = \frac{3 + 8}{21} = \frac{11}{21} \\ \\ \frac{4}{5} + \frac{1}{7} = \frac{28 + 5}{35} = \frac{33}{35} \\ \\ \frac{2}{3} + \frac{1}{9} = \frac{6 + 1}{9} = \frac{7}{9}$

$\frac{1}{5} + \frac{4}{3} = \frac{3 + 20}{15} = \frac{23}{15} = 1 \frac{8}{15} \\ \\ \frac{5}{7} + \frac{1}{2} = \frac{10 + 7}{14} = \frac{17}{14} = 1 \frac{3}{14} \\ \\ \frac{1}{4} + \frac{3}{8} = \frac{2 + 3}{8} = \frac{5}{8} \\ \\ \frac{3}{5} + \frac{1}{9} = \frac{27 + 5}{45} = \frac{32}{45}$
