Question

Calcule:
0,2.0,3 / 3,2-20 se possível, qual seria a resposta em fração?

Answer 1

$\dfrac{(0,2).(0,3)}{3,2-2}= \dfrac{ \dfrac{2}{10} . \dfrac{3}{10} }{ \dfrac{32}{10} -2} = \dfrac{ \dfrac{1}{5} . \dfrac{3}{10} }{ \dfrac{16}{5} -2}= \dfrac{ \dfrac{3}{50}}{ \dfrac{16-10}{5}}= \dfrac{ \dfrac{3}{50}}{ \dfrac{6}{5}}=\dfrac{3}{50}.\dfrac{5}{6}$$=\dfrac{1}{10}.\dfrac{1}{2}=\dfrac{1}{20}$
