[Nguyễn Thị Thương Hoài]

\(\dfrac{3}{5}\) = \(\dfrac{3\times2}{5\times2}\) = \(\dfrac{6}{10}\) = \(\dfrac{6:2}{10:2}\) = \(\dfrac{3}{5}\) = \(\dfrac{3\times3}{5\times3}\) = \(\dfrac{9}{15}\) = \(\dfrac{9\times2}{15\times2}\) = \(\dfrac{18}{30}\)

Vậy \(\dfrac{3}{5}\) = \(\dfrac{6}{10}\) = \(\dfrac{9}{15}\) = \(\dfrac{18}{30}\)
