I solved my problem by specifying the column range
 #+tblfm: @address@hidden = ($3 / $2) * 100

I cannot help with the OP's question but this table leads to very
strange behaviour for me.  If I delete the tblfm lines, then go to the
location of the x variable (5th row, 2nd column) and type C-u C-c = to
enter "x=vsum(@address@hidden)", that is okay.  But if I then go to the next
column and try to enter the equivalent formula for y, it replaces the
previously entered formula for x!  If I go back to the x location and
re-enter that formula, it replaces the y formula.

Further, the formulae created by org are missing the $ in front of the
variable, i.e. x=vsum(...) instead of $x=vsum(...).

This happens with up to date org from git as of an hour or so ago.

For the OP, the formulas
