\(x:\frac{-1}{2}.3=\frac{-1}{2}\)
\(x:\frac{-1}{2}=\frac{-1}{2}:3\)
\(x:\frac{-1}{2}=\frac{-1}{6}\)
\(x=\frac{-1}{6}.\frac{-1}{2}\)
\(x=\frac{1}{12}\)
Vậy \(x=\frac{1}{12}\).
\(x:\frac{-1}{2}=\frac{-1}{2}:3\)
\(x:\frac{1}{2}=\frac{1}{6}\)
\(x=\frac{1}{6}.\frac{1}{2}\)
\(x=\frac{1}{12}\)
Vậy \(x=\frac{1}{12}\).
x:(-1/2).3=-1/2
x:(-1/2) =-1/2:3
x:(-1/2) =1/6
x=1/6.1/2
x=1/12
