\n" ); document.write( "cross multiply
\n" ); document.write( " $\"+100x+=+55%28640%29+\"$
\n" ); document.write( "divide both sides by 100
\n" ); document.write( " $\"+x+=+55%28640%29%2F100+\"$
\n" ); document.write( "reduce/divide
\n" ); document.write( " $\"+x+=+55%2864%29%2F10+\"$
\n" ); document.write( " $\"+x+=+11%2864%29%2F2+\"$
