Explicación paso a paso:
[tex] \frac{9}{4 } - \frac{3}{11} \times ( \frac{23}{3} - \frac{1}{2} \times \frac{13}{5}) - 5 = \frac{9}{4} - \frac{ 3}{11} \times ( \frac{23}{3} - \frac{13}{6}) - 5 = \frac{9}{4} - \frac{3}{11} \times \frac{11}{2} - 5 = \frac{9}{4} - 3 \times \frac{1}{2} - 5 = \\ \frac{9}{4} - \frac{3}{2} - 5 = - \frac{17}{4} [/tex]
espero que te sirva xd
