\(\frac{4}{x}\) \(=\frac{1}{5}\)
Ta có :
\(\frac{4}{x}\) \(=\frac{4}{20}\)
=> \(x=20\)
#Ninh Nguyễn
x.1=4.5
x.1=20
x=20:1
x=20
x.1 = 4.5
x.1 = 20
x = 20
Vậy x = 20
x = 20 nha
:))
\(\frac{4}{x}=\frac{1}{5}\)
\(\Rightarrow\)\(4\times5=1\times x\)
\(\Rightarrow\)\(20=x\)
\(\Rightarrow\)\(x=20\)
Vậy \(x=20\)
x= 4/20 nha bạn
