Swapping the numbers changes everything. 10/12 is less than one whole; 12/10 is more than one whole. The bottom number always says how many equal parts make up the whole.
A pie with 10 filled and 2 empty is not 10/2. That compares the filled part to the empty part. The bottom number counts all 12 parts, filled or not.
