Select all of the equations below in which $k$ is inversely proportional to $m$. \[ k=\frac{m}{2} \quad k=2 m \quad k=m-2 \] \[ k=m+2 \quad k=\frac{2}{m} \]

Step 1 ：First, we need to find the equations where \(k\) is equal to a constant divided by \(m\). In other words, we are looking for equations in the form of \(k = \frac{C}{m}\), where \(C\) is a constant.

Step 2 ：Given equations are: \(k=\frac{m}{2}\), \(k=2m\), \(k=m-2\), \(k=m+2\), and \(k=\frac{2}{m}\).

Step 3 ：Among these equations, only \(k=\frac{2}{m}\) is in the form of \(k = \frac{C}{m}\), where \(C = 2\).

Step 4 ：\(\boxed{k = \frac{2}{m}}\) is the only equation in which \(k\) is inversely proportional to \(m\).
