\n" ); document.write( "\n" ); document.write( "3.2 = 16/5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the imperfect roots are irrational ___ sqrt(2) , cuberoot(7) , etc.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "rational numbers are real , but not all real numbers are rational ___ pi, e and the above roots are examples\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "integer, whole, and natural numbers are rational ___ but not necessarily vice-versa
