We have the proportion:


(4)/(9)=(x)/(54)

We can cross the denominator in each side as a product to the other side of the equality as:


4\cdot54=x\cdot9

Then, we can solve for x:


\begin{gathered} 4\cdot54=x\cdot9 \\ x=4\cdot(54)/(9) \\ x=4\cdot6 \\ x=24 \end{gathered}

Answer: x=24

NOTE: in this case, I put the 9 again as denominator because 54/9 is a easy to calculate quotient without calculator.
