Question

1/3+Xx5/6-1/6=2/3

 

Answer 1

\(\frac{1}{3}+x\times\frac{5}{6}-\frac{1}{6}=\frac{2}{3}\)

\(\Rightarrow x\times\frac{5}{6}-\frac{1}{6}=\frac{2}{3}-\frac{1}{3}=\frac{1}{3}\)

\(\Rightarrow x\times\frac{5}{6}=\frac{2}{6}+\frac{1}{6}=\frac{1}{2}\)

\(\Rightarrow x=\frac{1}{2}\times\frac{6}{5}=\frac{3}{5}\)

Answer 2

tk : aichoichuberong

mk : rongbechuchoiai

Answer 3

\(\frac{1}{3}+\frac{x\times5}{6}-\frac{1}{6}=\frac{2}{3}\)

\(\Rightarrow\frac{x\times5}{6}=\frac{2}{3}-\frac{1}{3}-\frac{1}{6}\)

\(\Rightarrow\frac{x\times5}{6}=\frac{1}{3}-\frac{1}{6}=\frac{1}{6}\)

\(\Rightarrow\frac{x\times5}{6}=\frac{1}{6}\)

\(\Rightarrow x\times5=1\)

\(\Rightarrow x=\frac{1}{5}\)

Answer 4

\(\frac{1}{3}+\frac{x\times5}{6}-\frac{1}{6}=\frac{2}{3}\)

\(\Rightarrow\frac{x\times5}{6}=\frac{2}{3}-\frac{1}{3}+\frac{1}{6}\)

\(\Rightarrow\frac{x\times5}{6}=\frac{1}{2}=\frac{3}{6}\)

\(\Rightarrow x\times5=3\)

\(\Rightarrow x=\frac{3}{5}\)

Answer 5

mk nhầm

Answer 6

\(\frac{1}{3}\) +\(x\)  \(\times\) \(\frac{5}{6}-\frac{1}{6}\) =\(\frac{2}{3}\)

\(\frac{1}{3}+x\times\frac{5}{6}\)=\(\frac{2}{3}+\frac{1}{6}\)

\(\frac{1}{3}+x\times\frac{5}{6}\) =\(\frac{5}{6}\)

\(\frac{1}{3}+x=\frac{5}{6}\div\frac{5}{6}\)

\(\frac{1}{3}+x=1\)

        \(x=1-\frac{1}{3}\)

      \(x=\)\(\frac{2}{3}\)

Answer 7

\(\frac{1}{3}+x\cdot\frac{5}{6}-\frac{1}{6}=\frac{2}{3}\)

\(\frac{1}{3}+x\cdot\frac{5}{6}=\frac{2}{3}+\frac{1}{6}\)

\(\frac{1}{3}+x\cdot\frac{5}{6}=\frac{5}{6}\)

\(x\cdot\frac{5}{6}=\frac{5}{6}-\frac{1}{3}\)

\(x\cdot\frac{5}{6}=\frac{1}{2}\)

\(x=\frac{1}{2}:\frac{5}{6}\)

\(x=\frac{3}{5}\)
