Question

qual é o valor da expressão 1/3+1/4-5/6 sobre 1/2

Answer 1

$\dfrac{ \frac{1}{3} + \frac{1}{4} - \frac{5}{6}}{ \frac{1}{2}} \\\\ \dfrac{ \frac{4+3-10}{12}}{ \frac{1}{2}} \\\\ \dfrac{ \frac{-3}{12}}{ \frac{1}{2}} \\\\ \dfrac{-3}{12} * { \frac{2}{1}} \\\\ \dfrac{-6}{12} \\\\ \dfrac{-1}{2}$
