eliminating '1.0' when divided by float numbers

Maxima 5.25

Hi. say I have an equation like

3 = 3.5 %e^( ...);

then, I want to eliminate '3.5', so I divide the whole thing by 3.5.

%/3.5;

it gives,

... = 1.0 %e^(...)


'1.0' remains there.  Of course there is no influence in terms of math, but
it matters if I want to take log of it,

log(%);

gives,

... = log(1.0 %e^(...))

Is there anyway to eliminate '1.0' so that it becomes easier to compute it?
