\(\frac{x}{6}=\frac{1}{2}+\frac{1}{3}.\frac{3}{4}\)
<=> \(\frac{x}{6}=\frac{1}{2}+\frac{3}{12}\)
<=>\(\frac{x}{6}=\frac{1}{2}+\frac{1}{4}\)
<=>\(\frac{x}{6}=\frac{2}{4}+\frac{1}{4}\)
<=>\(\frac{x}{6}=\frac{3}{4}\)
<=>\(x=\frac{3}{4}.6\)
<=>\(x=\frac{9}{2}\)
kl:
\(\frac{x}{6}=\frac{1}{2}+\frac{1}{3}\times\frac{3}{4}\)
\(\frac{x}{6}=\frac{1}{2}+\frac{1}{4}\)
\(\frac{x}{6}=\frac{3}{4}\)
\(\frac{3}{4}=\frac{9}{12}\)
\(\frac{9}{12}=\frac{4,5}{6}\)
Vậy x = 4,5
\(\frac{x}{6}=\frac{3}{4}\)
\(3.6=x.4\)
\(18=4x\)
\(x=18:4=4,5\)
Chắc là được rồi đó bn
