\(x:\dfrac{7}{11}=\dfrac{5}{7}\Leftrightarrow x=\dfrac{5}{7}.\dfrac{7}{11}=\dfrac{5}{11}\)
\(x:\dfrac{7}{11}=\dfrac{5}{7}\\ x=\dfrac{5}{7}\times\dfrac{7}{11}\\ x=\dfrac{35}{77}\)
\(x\div\dfrac{7}{11}=\dfrac{4}{7}+\dfrac{1}{7}\)
\(x\div\dfrac{7}{11}=\dfrac{5}{7}\)
\(x=\dfrac{5}{7}\times\dfrac{7}{11}\)
\(x=\dfrac{5}{11}\)
