All this can be is a ratio of 3 numbers,
for instance, the ratio of the 3 dimensions
of a rectangular box.
---------------------
Then you compare with another box
2/1/8 = a/b/c
---------------------
UNLESS:
You know you have:
+2%2F%28%281%2F8%29%29+, then this just an ordinary fraction that
asks: how many times does +1%2F8+ go into +2+ ?
( +16+ times )
-------------------
Notice this is not the same as
+%28%28+2%2F1+%29%29%2F8+ which is +1%2F4+
