If I know the percentage by weight of elements in a formula I can calculate the relative ratios of atoms in the formula no problem.(adsbygoogle = window.adsbygoogle || []).push({});

What I can't figure out is how to turn that ratio into an empirical formula.

To put it mathematically how do I turn a decimal number into a an approximate fraction of small integers?

#.## = ?/?

Thanks
