Question

Poderiam responder para mim

Answer 1

Resposta:

2) 6/6 ou 1

3) 1/3

Answer 2

Resposta:

$\frac{2}{3(2)} + \frac{5}{6(1)} - \frac{1}{2(3)} = \frac{4}{6} + \frac{5}{6} - \frac{3}{6} = \frac{6}{6} = 1$

$( - \frac{3}{6} ) - ( + \frac{5}{4} ) \times ( - \frac{2}{3} ) \\ = - \frac{ 3}{6} - \frac{5}{4} \times ( - \frac{2}{3} ) \\ = - \frac{3}{6(2)} + \frac{10}{12(1)} \\ = - \frac{6}{12} + \frac{10}{12} \\ = \frac{7}{12}$
