\n" ); document.write( "\n" ); document.write( " $\"%2830%2F100%29+%2A+m+=+645.00\"$
\n" ); document.write( "next, multiply both sides by 100/30
\n" ); document.write( " $\"+m+=+%28100%2F30%29+%2A+645.00+\"$
\n" ); document.write( "solve the right side
\n" ); document.write( " $\"+m+=+2150+\"$
\n" ); document.write( "check: is 30% of this 645.00?
\n" ); document.write( " $\"+%2830%2F100%29+%2A+2150+=+645+\"$
