We didn't use to think so, but after Homeland Security stopped him at the airport in July and found a strange substance in the heel of his shoe, things have sort of snowballed, what with their search of his house turning up an altar to Sigma and the French 7's locked away behind the false wall in the basement whose little crossbars he had been cutting off to offer on the altar, leaving them just ordinary 1's and after the obligatory "he was the nicest decimal you ever met, I would never have suspected...'s" from his neighbors appeared on local TV, calls rolling in from numbers and decimals — AND fractions, if you can believe he crossed THAT barrier! — from bars in nearby cities all announcing he was the nastiest freak any of them ever met, and creepy too (it just broke my heart to hear little 68.4's story about how he hounded her with that "match made in heaven" talk).
All in all, I'm not a doctor, either of pyshcology or math, but I believe history will remember .6 as irrational, and a disgusting to another day and age, even if, technically, he was made from the joining of natural numbers.
(Seriously though, no, .6 is not irrational. It would only be irrational if it could not be expressed as a fraction made up of whole numbers. Since we can express it so, it is rational.)

No, .6 is perfectly rational.
An irrational number is a number that cannot be expressed as a fraction.
0.6 can be expressed as 6/10, or 3/5.
Pi is an irrational number. So is phi, if I recall correctly.

Wrong. An irrational number is a number that can't be written as a fraction. .6 is 3/5.

Wrong! It's a rational number equal to 6/10 or 3/5.
Rational numbers have terminating or repeating
decimal expansions. Irrational numbers don'r.

0.6 is a rationals number
rational numbers are defined as numbers which can be expressed in the form of p/q
where p & q are integers and q is not 0
0.6 can be expressed as 6/10 or 3/5
examples of irrational numbers are pi or sq.root 2 etc

an irrational number is a fraction in which the numerator is greator than the denominator. eg. 4/3 or 3/2.

0.{whatever n digits} is a rational number because we could alway express it as a ratio of two integers:
{whatever n digits}/(10^n) .
0.425309842858309568095658 is a rational number because we could express it as a ratio of two integers:
425309842858309568095658 / 100000000000000000000000 .
Therefore without question 0.6 is rational.
However, 0.6 is not a natural number.
Perhaps your question could have been
"Is 0.6 a natural number?"
A natural number can be used for ordinal and integral cardinal operations.
Ordinal numbers - for ordering and sequencing.
Integral Cardinal numbers - integer numbers used for counting whole items.
Therefore, they are integers.
The convention seems to be that a natural number has to be positive too (am I right?)
Irrational numbers are because we don't have an exact numerical representation for it:
pi
square, cube, quad roots of 2
sqrt of 3
sqrt of 5
e
... et cetera

no its rational. any decimal that terminates or ends is rational.
Pi on the other hand is irrational because it goes on forever.
