Question

quien me ayuda con esto

Answer 1

Completa la tabla
Solucion:
$\frac{3}{7} + \frac{-24}{42} = \frac{-42}{42} = \frac{-6}{6}$
$\frac{5}{20} - \frac{7}{5} = \frac{2}{20}$
$\frac{9}{2} . \frac{3}{7} = \frac{27}{14}$
$- \frac{4}{2} : \frac{11}{5} = -\frac{20}{22}$
$\frac{-5}{2}+ \frac{5}{7} = \frac{5}{14 }$
$\frac{-8}{5} - \frac{9}{6} = -\frac{93}{30}$

Espero que te sirva
