The following is really ugly, but does what I think you're after. I'm
sure you could turn this into something prettier by defining a macro so
you only needed to type in each equation once. Also the display maths
doesn't seem to take up quite as much space as the equation environment,
so I had to fiddle with the dummy equation number to get \eqwidth to be
big enough to avoid the equation number ending up on its own line.
Hope this helps. Be sure not to leave any blank lines or you'll get the
minipages as separate paragraphs!

\documentclass{article}
\newlength{\eqwidth}
\begin{document}
This is a test
\settowidth{\eqwidth}{$$a=b (10.5555)$$}
\begin{minipage}{\eqwidth}
\begin{equation} a=b\end{equation}
\end{minipage} \hfill
%
\settowidth{\eqwidth}{$$a=b (10.5555)$$}
\begin{minipage}{\eqwidth}
\begin{equation} a=b\end{equation}
\end{minipage} \hfill
%
\settowidth{\eqwidth}{$$a=b (10.5555)$$}
\begin{minipage}{\eqwidth}
\begin{equation} a=b\end{equation}
\end{minipage} \hfill

\settowidth{\eqwidth}{$$aaaaaaaaaaaaaaaaaaaaaaaa=baaaaaaaaaaaaaaaa
(10.5555555)$$}
\begin{minipage}{\eqwidth}
\begin{equation}
aaaaaaaaaaaaaaaaaaaaaaaa=baaaaaaaaaaaaaaaa\end{equation}
\end{minipage} \hfill

\settowidth{\eqwidth}{$$a=b (10.5555)$$}
\begin{minipage}{\eqwidth}
\begin{equation} a=b\end{equation}
\end{minipage} \hfill
%
\settowidth{\eqwidth}{$$a=b (10.5555)$$}
\begin{minipage}{\eqwidth}
\begin{equation} a=b\end{equation}
\end{minipage} \hfill
That's it?
