ayuda por favor ​

Answer 1

Respuesta:

$a) \frac{33}{30}$

$b) \frac{82}{6}$

Explicación paso a paso:

$a) \frac{19}{30} +\frac{23}{30}+ (-\frac{9}{30})=\\\frac{42}{30} - \frac{9}{30} = \frac{33}{30}$

$b) (\frac{19}{3} + 8 ) + (\frac{11}{6} - \frac{5}{2}) =\\\\(\frac{19}{3} + \frac{24}{3}) + ( \frac{11}{6} - \frac{15}{6}) =\\\\\frac{43}{3} + (- \frac{4}{6} ) = \\\\\frac{86}{6} - \frac{4}{6} = \frac{82}{6}$
