Answer 1

Respuesta:

$1) - \frac{5}{2} + \frac{2}{3} = - \frac{15}{6} + \frac{4}{6} = - \frac{11}{6}$

$2) - \frac{5}{7} + ( - \frac{1}{14} ) = - \frac{10}{14} + ( - \frac{1}{14} ) = - \frac{11}{14}$

$3) \frac{3}{7} - \frac{1}{5} = \frac{15}{35} - \frac{7}{35} = \frac{8}{35}$

$4) - \frac{8}{3} - \frac{1}{2} = (- \frac{8}{3} ) + ( - \frac{1}{2} ) = ( - \frac{16}{6} ) + ( - \frac{3}{6} ) = - \frac{19}{6}$

$5) - \frac{5}{6} - ( - \frac{1}{5} ) = - \frac{5}{6} + \frac{1}{5 } = - \frac{25}{30} + \frac{6}{30} = - \frac{19}{30}$
