Question

4 sobre 2 . 2 -6 sobre 1 + 2 sobre 4 . 2 sobre 2

Answer 1

$\frac{4}{2} . \frac{2 - 6}{1} + \frac{2}{4} . \frac{2}{2}$

$\frac{4}{2} . \frac{ - 4}{1} = \frac{ - 16}{2} = - 8$

$\frac{2}{4} . \frac{2}{2} = \frac{4}{8}$

$\frac{ - 8}{1} + \frac{4}{8} \\ mmc = 8 \\ \frac{ - 64}{8} + \frac{4}{8} = \frac{ - 60}{8} ^{ \div 4} = \frac{ - 15}{2}$
