Como faço essas questões?
A) -3/5.4/6=?
B)6/12;(-3/8)=
E)(-2/7)2 =?
F)(2/6)-2

Answer 1

a)

$( - \frac{3}{5} ).( \frac{4}{6}) = - \frac{12 \div 6}{30 \div 6} = - \frac{2}{5}$

b)

$\frac{6}{12} \div ( - \frac{3}{8}) \\ \frac{6}{12}.( - \frac{8}{3}) = - \frac{48 \div 12}{36 \div 12} = - \frac{4}{3}$

e)

$- ( \frac{2}{7} ).2 = - \frac{4}{7}$

f)

$\frac{2}{6} - 2 = \frac{2}{6} - \frac{12}{6} = - \frac{10 \div 2}{6 \div 2} = - \frac{5}{3}$
