Inverse variation: find the constant and missing values
The variables \(x\) and \(y\) have the following variation relationship
\[y \propto \frac{1}{x}\]
A known pair is \((2, \frac{15}{8})\) in the \((x,y)\) order
| x | \(2\) | \(5\) | ? | \(40\) |
|---|---|---|---|---|
| y | \(\frac{15}{8}\) | \(0.75\) | \(\frac{15}{32}\) | ? |
