Answer 2

Resposta:

$\frac{4}{5} ~.~2=\frac{8}{10} =8~:~10=0,8\\ \\ \frac{7}{4} ~.~5=\frac{35}{20} =\frac{35}{20}:2= \frac{17,5}{10}=1,75\\ \\ \frac{5}{8} ~.~5=\frac{25}{40} =\frac{25}{40}:4= \frac{6,25}{10}=0,625\\ \\ \frac{11}{5} ~.~4=\frac{44}{20} =\frac{44}{20}:2= \frac{22}{10}=2,2\\ \\ \frac{13}{6} ~.~5=\frac{65}{30} =\frac{65}{30}:3= \frac{21,666...}{10}=2,1666...$
