Question

Porfavor alguien me ayuda​

Answer 1

Respuesta:

$\frac{4}{13} - \frac{1}{13} + \frac{9}{13} = \frac{12}{13}$

$\frac{3}{2} + ( - \frac{5}{6} ) + \frac{7}{4} = \frac{18}{12} - \frac{10}{12} + \frac{21}{12} = \frac{29}{12}$

$\frac{10}{9} - \frac{5}{3} - \frac{4}{9} = \frac{10}{9} - \frac{15}{9} - \frac{4}{9} = - \frac{9}{9} = - 1$

$\frac{8}{5} + \frac{3}{8} - \frac{5}{7} = \frac{448}{280} + \frac{105}{280} - \frac{200}{280} = \frac{353}{280}$
