The last column is the ratio between column b and a, the last row is the
sum of
each row, the second formula only applies from the second row to the row
before
last row. The table that doesn't work is:
| | a | b | ratio |
| | 0.797 | 0.780 | |
| | 0.744 | 0.730 | |
| | 12.707 | 2.384 | |
| sum | 14.248 | 3.114 | 0.92040988 |
| ^ | x | y | |
#+tblfm: $x=vsum(@2..@-1) :: $y=vsum(@3..@-1)
#+tblfm: $4 = ($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(@2..@i-1)", 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

I solved my problem by specifying the column range
#+tblfm: @2$4..@-2$4 = ($3 / $2) * 100
