a, \(\dfrac{5}{6}\) = \(\dfrac{10}{12}\) = \(\dfrac{30}{36}\) b, \(\dfrac{40}{16}\) = \(\dfrac{10}{4}\) = \(\dfrac{200}{80}\)
c, \(\dfrac{9}{12}\) = \(\dfrac{3}{4}\) = \(\dfrac{54}{72}\) d, \(\dfrac{84}{21}\) = \(\dfrac{28}{7}\) = \(\dfrac{4}{1}\)
\(\dfrac{20}{35}\) = \(\dfrac{20:5}{35:5}\) = \(\dfrac{4}{5}\) vậy \(\dfrac{4}{5}=\dfrac{20}{35}\)
\(\dfrac{5}{8}\) = \(\dfrac{5\times5}{8\times5}\) = \(\dfrac{25}{40}\)
\(\dfrac{28}{35}\) = \(\dfrac{28:7}{35:7}\) = \(\dfrac{4}{5}\)
