There is a way that \"non-math\" types prefer, but I can't remember it. Maybe someone else will contribute that method. I prefer to just set up an equation, where x is the unknown number, and solve for x.\r

\n" ); document.write( "\n" ); document.write( "First, \"50%\" means .50, \"what #\" means x, and \"is\" means equals.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The equation reads:\r
\n" ); document.write( "\n" ); document.write( "\".50x+=+30+\"\r
\n" ); document.write( "\n" ); document.write( "To solve for x, just divide both sides by .50\r
\n" ); document.write( "\n" ); document.write( "\".50x%2F.50+=+30%2F.50+\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use a calculator, or multiply numerator and denominator by 10 to get 300/5.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"+x+=+60+\"
