Well...\r
\n" ); document.write( "\n" ); document.write( "We need to set up a proportion. Here is how we do it.\r
\n" ); document.write( "\n" ); document.write( "4=12
\n" ); document.write( "x=66\r
\n" ); document.write( "\n" ); document.write( "Now we cross multiply.\r
\n" ); document.write( "\n" ); document.write( "4*66=264
\n" ); document.write( "12*x=12x\r
\n" ); document.write( "\n" ); document.write( "Now to isolate the variable by dividing both sides by 12
\n" ); document.write( "12x/12=x
\n" ); document.write( "264/12=22\r
\n" ); document.write( "\n" ); document.write( "x=22\r
\n" ); document.write( "\n" ); document.write( "John will read 22 books in 4 months
\n" ); document.write( "
