If you want to solve for R, then you must eliminate or undo everything that has been done to R. In this problem, R is multiplied by P and T. In order to "undo" multiplication, you must DIVIDE both sides by P and T.
I=+P%2AR%2AT
I%2F%28P%2AT%29+=+%28P%2AR%2AT%29%2F%28P%2AT%29

The P and T divide out, and you are left with
I%2F%28P%2AT%29+=+R
