\(\frac{1}{2}=0,5\);\(\frac{1}{5}=0,2\)
Ta có:\(0,5:x=0,2\)
=> \(x=0,5:0,2\)
=> \(x=2,5\)
Vậy \(x=2,5\)
\(\frac{1}{2}:x=\frac{1}{5}\)
\(\Rightarrow x=\frac{1}{2}:\frac{1}{5}\)
\(\Rightarrow x=\frac{1}{2}\cdot\frac{5}{1}\)
\(\Rightarrow x=\frac{5}{2}\)
\(\Rightarrow x=2,5\)
\(\frac{1}{2}\): x = \(\frac{1}{5}\)
x = \(\frac{1}{2}:\frac{1}{5}\)
x = 2,5
