Question

calcule e simplifique 3 sobre 4 mais 5 sobre 6 menos 1 sobre 2​

Answer 1

$\frac{3}{4} + \frac{5}{6} - \frac{1}{2} \\ \frac{3}{4} \times (3) = \frac{9}{12} \\ \frac{5}{6} \times (2) = \frac{10}{12} \\ \frac{1}{2} \times (6) = \frac{6}{12} \\ \frac{9}{12} + \frac{10}{12} - \frac{6}{12} \\ \frac{13}{12}$
