\(3:2\frac{1}{4}=\frac{3}{4}:\left(6x\right)\)
\(3:\frac{9}{4}=\frac{3}{4}.6x\)
\(3.\frac{4}{9}=\frac{9}{2}x\)
\(\frac{4}{3}=\frac{9}{2}x\)
\(x=\frac{4}{3}:\frac{9}{2}=\frac{4}{3}.\frac{2}{9}=\frac{8}{27}\)
Ta có : 6x = \(2\frac{1}{4}.\frac{3}{4}:3=\frac{9}{16}\)
\(\Rightarrow x=\frac{9}{16}:6=\frac{3}{32}\)
\(3:2\frac{1}{4}=\frac{3}{4}:6x\)
\(\Rightarrow3:\frac{9}{4}=\frac{3}{4}:6x\)
\(\Rightarrow\frac{4}{3}=\frac{3}{4}:6x\)
\(\Rightarrow6x=\frac{3}{4}:\frac{4}{3}\)
\(\Rightarrow6x=\frac{3.3}{4.4}\)
\(\Rightarrow6x=\frac{9}{16}\)
\(\Rightarrow x=\frac{3}{32}\)
