Explanation:

Step1: Analyze wedge - dash formula

In a wedge - dash formula, the wedge represents a group coming out of the plane (towards the viewer), and the dash represents a group going into the plane (away from the viewer). The vertical bonds in Fischer projection are assumed to be going into the plane and the horizontal bonds are coming out of the plane.

Step2: Match groups' positions

For the given wedge - dash formula, the bromine ($Br$) is on a wedge (out of the plane), chlorine ($Cl$) is on a solid wedge (out of the plane), and the $-CH_2OH$ group is on a dash (into the plane). When converting to Fischer projection, the $-CH_3$ group is on the top vertical position, $Br$ is on the left - hand side (horizontal), $Cl$ is on the right - hand side (horizontal) and $CH_2OH$ is at the bottom vertical position.
