Observe that the decimal (0.19) of the number is repeating, so the number ![\"\"](\"http://c4anything.com/MathKey/fckeditor/editor/plugins/fckeditor_wiris/integration/showimage.php?formula=603c03fbf3f887bd05b63224128b5dc3.png\")
is a rational number.
§ Observe the Venn diagram:
\§ The number is not a Natural number (N), not a Whole number (W), and not an Integer (Z).
§ The number is a rational number (Q). \ \
§ All rational numbers (Q) are real numbers (R), ![\"\"](\"/userfiles/image/realnumber.jpg\")
![\"\"](\"/userfiles/image/steps_images/solution.JPG\")
The number belongs to Q and R.
