ANSWER

72 : 32 = 9 : 4

Explanation

Let the missing value be x

Hence, the proportion becomes x : 32 = 9 : 4

ratio means division

Mathematically, we have the below expression


\begin{gathered} (x)/(32)\text{ = }(9)/(4) \\ \text{Cross multiply} \\ 4\cdot\text{ x = 32 }\cdot\text{ 9} \\ 4x\text{ = 288} \\ \text{Divide both sides by 4} \\ (4x)/(4)\text{ = }(288)/(4) \\ x\text{ = 72} \end{gathered}

Since the value of x is 72

Therefore, 72 : 32 = 9 : 4
