by definition, the rational ones are the ones that can be written in the form $\"a%2Fb\"$ where and $\"b\"$ are integers and $\"b\"$ does not equal $\"0\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"15=15%2F1\"$ - $\"rational\"$ number\r
\n" ); document.write( "\n" ); document.write( " $\"219=219%2F1\"$ - $\"rational\"$ number\r
\n" ); document.write( "\n" ); document.write( " $\"sqrt%289%29=3=3%2F1\"$ - $\"rational\"$ number\r
\n" ); document.write( "\n" ); document.write( " $\"3995=3995%2F1000\"$ - $\"rational\"$ number\r
\n" ); document.write( "\n" ); document.write( "so, { $\"15\"$ , $\"219\"$ , $\"sqrt%289%29\"$ , $\"+3.995\"$ }- the set of numbers contain $\"rational\"$ numbers \n" ); document.write( "

\n" );
