Me ayudan en esto por favor?

Answer 1

a)

$\frac{119}{19} + \frac{18}{19} - \frac{6}{19} = \\ \\ \frac{119 + 18 - 6}{19} \\ \\ = \frac{131}{19}$

b)

$\frac{4}{11} + \frac{23}{11} - \frac{5}{11} = \\ \\ \frac{4 + 23 - 5}{11} \\ \\ = \frac{22}{11} = 2$

c)

$\frac{15}{14} + \frac{1}{3} - \frac{1}{2} = \\ \\ \frac{45 + 14 - 21}{42} \\ \\ \frac{38}{42} = \frac{19}{21}$

d)

$\frac{1}{5} + \frac{1}{3} + \frac{11}{6} = \\ \\ \frac{6 + 10 + 55}{30} \\ \\ = \frac{71}{30}$
