Common mix-ups with 5/8
Swapping the numbers changes everything. 5/8 is less than one whole; 8/5 is more than one whole. The bottom number always says how many equal parts make up the whole.
A pie with 5 filled and 3 empty is not 5/3. That compares the filled part to the empty part. The bottom number counts all 8 parts, filled or not.
