If 12 then 5. If 10 then how many?\r
\n" ); document.write( "\n" ); document.write( "12 -> 5\r
\n" ); document.write( "\n" ); document.write( "10 -> x\r
\n" ); document.write( "\n" ); document.write( "now by forming the rate we have this\r
\n" ); document.write( "\n" ); document.write( "12/10=5/x\r
\n" ); document.write( "\n" ); document.write( "and it's not direct proportion then we have\r
\n" ); document.write( "\n" ); document.write( "12/10=x/5 after multiplication side to side by 10 we have\r
\n" ); document.write( "\n" ); document.write( "12=2*x\r
\n" ); document.write( "\n" ); document.write( "x=6\r
\n" ); document.write( "\n" ); document.write( "there are 6 machines
\n" ); document.write( "have a nice day
\n" ); document.write( "
\n" );
