Question

Calcule o valor das expressões
(5/2 - 4/3) - (2/2 + 6/3)

Answer 1

$(\frac{5}{2} - \frac{4}{3} ) - ( \frac{2}{2} + \frac{6}{3} ) = - \frac{11}{6}$

Answer 2

$( \frac{5}{2} - \frac{4}{3}) - ( \frac{2}{2} + \frac{6}{3}) \\ (\frac{15 - 8}{6}) - ( \frac{6 + 12}{6}) \\ \frac{7}{6} - \frac{18}{6} \\ ( \frac{ - 11}{6})$
