X:\(\frac{2}{3}=\frac{5}{6}\)
\(\Leftrightarrow\)X=\(\frac{5}{6}\).\(\frac{2}{3}\)
\(\Leftrightarrow\)X=\(\frac{5}{9}\)
\(x\div\frac{2}{3}=\frac{5}{6}\)
\(x=\frac{5}{6}\times\frac{2}{3}\)
\(x=\frac{5}{9}\)
\(x:\frac{2}{3}=\frac{5}{6}\)
\(x\) \(\) \(=\frac{5}{6}\)x\(\frac{2}{3}\)
\(x\) \(=\frac{10}{18}\)
\(x\) \(=\frac{5}{9}\) (Đây là phân số tối giản nha bạn)
