$\boxed{\begin{array}{lr}a) \: \frac{6}{8} \: de \: 656 = 6 \times 82 = 492 \\ \\ b) \: \frac{1}{5} \: de \: 75 = \frac{1}{ \cancel{5}} \times \cancel{75} = 15 \\ \\ c) \: \frac{2}{5} \: de \: 75 = 2 \times 15 = 30 \\ \\ d) \: \frac{1}{3} \: de \: 2016 = \frac{1}{ \cancel{3}} \times 2 \cancel{01}6 = 672 \\ \\ e) \: \frac{1}{2} \: de \: 56 = \frac{1}{ \cancel{2}} \times \cancel{56} = 28 \\ \\ f) \: \frac{4}{7} \: de \: 21 = 4 \times 3 = 12 \end{array}}$
