Rational
All whole numbers are rational. Any rational number divided by another (non-zero) rational number is a rational number.
RATIONAL , because you can convert it to a RATION (FRACTION). Method Let P = 0.272727.... Then 100P = 27.272727.... Subtract 99P = 27 (Note the decimals to infinity subtract to zero. P = 27/99 Cancel down by '9' P = 3/11 ( Which is a RATIO/rational). Since both '3' & '11' are prime numbers this will not cancel down any further. Hence 3/11 = 0.272727....
It is a rational number.
