Does this do it like you want ?

expr=(3.4*10^62 + 4.5*10^63 x)/(6.7*10^64 + 8.9*10^63 x)

Simplify //@ (Factor /@ expr)

Greetings

Objet : [mg48761] Reduction of Coefficients Coming Out of Solve

A rational polynomial result from Solve multiplies every coefficient by
a large factor of 10, e.g. 10^62.   Neither Simplify nor FullSimpify
remove this common factor from the numerator and denominator.  I can
remove it by hand but there must be a Mathematica trick that removes it.

What might it be?

For example:

(3.4*10^62 + 4.5*10^63 x)/(6.7*10^64 + 8.9*10^63 x).

Thanks for any insight.

Cheers, Scott
