Question

2/3x15/4-(1/6x1/12+1/8)

Answer 1

$\frac{2}{3}* \frac{15}{4}- ( \frac{1}{6}* \frac{1}{12} + \frac{1}{8})= \\ \\ Resolvemos \ la \ multiplicaci\'on \ dentro \ del \ par\'entesis \\ \\ \frac{2}{3}* \frac{15}{4}- ( \frac{1}{72} + \frac{1}{8})= \\ \\ Resolvemos \ la \ suma \ dentro \ del \ par\'entesis \\ \\ \frac{2}{3}* \frac{15}{4}- ( \frac{1+9}{72})= \\ \\ \frac{2}{3}* \frac{15}{4}- \frac{10}{72}= \\ \\ \frac{2*15}{3*4}- \frac{10}{72}= \\ \\ \frac{5}{2}- \frac{5}{36}= \frac{90-5}{36} = \boxed{ \frac{85}{36}}$

Espero que te sirva, salu2!!!!
