The numerator is a binary integer, not a bit (and not the part of the number before the "decimal" point).

3 in binary is 11. 6 in binary is 110.

3/2 (decimal) is 11/10 (binary) and 6/4 (decimal) is 110/100 (binary).

Of course the denominators always have trailing zeros, so can be (and are) represented more compactly.
