\(4\cdot3=2\cdot6\)
nên \(\dfrac{4}{2}=\dfrac{6}{3};\dfrac{4}{6}=\dfrac{2}{3};\dfrac{2}{4}=\dfrac{3}{6};\dfrac{6}{4}=\dfrac{3}{2}\)
4.3 = 2.6
\(\Rightarrow\) \(\dfrac{4}{2}=\dfrac{6}{3}\) ; \(\dfrac{4}{6}=\dfrac{2}{3}\) ; \(\dfrac{3}{2}=\dfrac{6}{4}\) ; \(\dfrac{3}{6}=\dfrac{2}{4}\)
\(\dfrac{4}{2}=\dfrac{6}{3};\dfrac{4}{6}=\dfrac{2}{3};\dfrac{3}{6}=\dfrac{2}{4};\dfrac{3}{2}=\dfrac{6}{4}\)
