\(x:2+x.\frac{1}{3}+x.\frac{1}{6}=1,8\)
\(x.\frac{1}{2}+x.\frac{1}{3}+x.\frac{1}{6}=1,8\)
\(x.\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{6}\right)=1,8\)
\(x.\left(\frac{3}{6}+\frac{2}{6}+\frac{1}{6}\right)=1,8\)
\(x.1=1,8\)
\(x=1,8\)
Vậy \(x=1,8\)
vậy 2 phần chia ra được 1 phần vậy =1/2
X x 1/2 +X x 1/3 +X x 1/6 =1,8
X x (1/2+1/3+1/6) =1,8
X x 1=1,8
X =1,8:1
X=1,8
