RE: fractional simplification

If you evaluate:
you will get

Dot (see help for Dot) is related to matrix or vector product. Since
neither a nor b have been defined as vector (and I suspect in your mind
a and b refer to numbers), the operation a.b has no special meaning for
a and b, therefore if b is a vector (like Dot suggests it should be),
b/b has no special meaning again.

Ordinary product is enter either by a space like "a b" or by a star

Hope this helps,

Subject: [mg11846] [mg11828] fractional simplification

We didn't manage to simplify the symbolic expression : "a . b/a" under
Mathematica 2.2.
We've tried using different functions like 'simplify' ...without success
Is it normal ?
Do you have any solutions to solve this problem ?
