400/28 = 1000/x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "400x = 28*1000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "400x = 28000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 28000/400\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 70\r
\n" ); document.write( "
\n" ); document.write( "
