doy corona quien me ayude​

Answer 1

Respuesta:

$a = \frac{1}{4} + \frac{2}{4} = \frac{3}{4} \\ b = \frac{2}{10} + \frac{3}{10} + \frac{4}{10} = \frac{9}{10} \\ \: c = \frac{2}{6} + \frac{3}{6} = \frac{5}{6} \\ d = \frac{5}{12} + \frac{4}{12} + \frac{2}{12} = \frac{11}{12} \\ e = \frac{2}{5} + \frac{2}{5} = \frac{4}{5} \\ f = \frac{2}{6} + \frac{1}{6} + \frac{2}{6} = \frac{5}{6}$

$a = \frac{4}{5} - \frac{2}{5} = \frac{2}{5} \\ b = \frac{8}{9} - \frac{4}{9} = \frac{4}{9} \\ c = \frac{6}{7} - \frac{3}{7} = \frac{3}{7} \\ d = \frac{8}{12} - \frac{1}{12} - \frac{2}{12} = \frac{5}{12} \\ e = \frac{10}{12} - \frac{2}{12} - \frac{3}{12} = \frac{5}{12} \\ f = \frac{8}{9} - \frac{2}{9} - \frac{3}{9} = \frac{1}{3}$
