Wet Ratio

Normal sudoku rules apply.

Each cage is either full of "oil" (even digits), full of "water" (odd digits), or a mix of both. In all cases, each "row" within a cage is of just one type (oil or water). Oil floats on water, so even digits will always be in rows above odd digits in mixed cages.

Digits in cages do not repeat.

Some cages contain clues that indicate the "Wet Ratio" (oil/water). That is, the sum of oil digits divided by the sum of water digits. For example, a 4-cell cage with a clue of 2/3 could be satisfied with (2+6) / (3+9). For the purposes of this puzzle, a number N divided by zero is defined to be infinity.
