Answer 3

\(\dfrac{22}{15}\) * \(x\) * \(\dfrac{63}{10}\) : \(\dfrac{9}{4}\) = \(\dfrac{36}{5}\)

\(\dfrac{22}{15}\) * \(x\) * \(\dfrac{63}{10}\)       = \(\dfrac{36}{5}\) * \(\dfrac{9}{4}\)

\(\dfrac{22}{15}\) * \(x\) * \(\dfrac{63}{10}\)       =  \(\dfrac{81}{5}\)

\(\dfrac{22}{15}\) * \(x\)                = \(\dfrac{81}{5}\) : \(\dfrac{63}{10}\)

\(\dfrac{22}{15}\) * \(x\)                =  \(\dfrac{18}{7}\)

        \(x\)                = \(\dfrac{18}{7}\) : \(\dfrac{22}{15}\)

        \(x\)                =     \(\dfrac{135}{77}\)
Vậy \(x\) = \(\dfrac{135}{77}\)
