No it is rational because 0.3 is equal to 3/10, both integers.
Examples of Irrational Numbers are pi, e, or sqrt(2).

Is a repeating decimal a rational or irrational number?
It is an irrational number. Actually it is a rational number. Think 2/3=.6666666, 1/9=.11111111.
Is the decimal form of an irrational number a repeating decimal?
An irrational number must not have a repeating sequence. If we have a number, such as 0.333333...., we can turn this into a rational number as such.Let x = 0.333333......, then multiply both sides by 10:10x = 3.333333......Now subtract the first equation from the second, since the 3's go on forever, they will cancel each other out and you're left with:9x = 3. Now divide both sides by 9: x = 3/9 which is 1/3, a rational number equal to 0.3333333....If a number can be expressed as the ratio a/b, where a and b are integers (with the restriction that b not equal zero), then the number is rational. If you cannot express the number as such, then it is irrational.
What is the decimal for 2 and 1 third?
Rounded to the nearest hundredth, it is 2.33. However, it is an irrational number with an infinite number of threes behind the decimal point (2.33333...) so it technically is 2.3 with a small horizontal line over the 3.
What is square root of 408?
It is an irrational number and it is 20.199 rounded to 3 decimal places
Is 13.001001001 a rational or irrational number and why?
A rational number is a number that can be expressed as a fraction. This means it can either be a terminating decimal or a recurring decimal. A terminating decimal is a decimal that doesn't recur (repeat for ever). A recurring decimal is a decimal that repeats a pattern of numbers after the decimal point. A good example of this is 1/3. 1/3 = 0.333333.... it is a rational number 13.001001001 is a rational number. Either you meant it to recur or not it makes no difference. 13.001001001 = 13 + 1001001/1000000000 as a terminating decimal 13.001001001....... = 12988/999 as a recurring decimal ---- Examples of numbers that are not rational: sqrt(2), pi, exp they are irrational as they cannot be expressed as fractions.
What does threes repeating on the calculator mean?
I'm going to assume that the threes are behind the decimal point. That means that the result is whatever number before the decimal point and 1/3. 1/3 is an irrational number. the 3s after the decimal point go on forever. If you're looking at 3s in front of the decimal point, you just have a large number with a lot of 3s just like you could have 1000000 or 10000000.
Is a repeating decimal a rational or irrational number?
It is an irrational number. Actually it is a rational number. Think 2/3=.6666666, 1/9=.11111111.
Is 1.5 a irrational number?
NO!!! Because 1.5 can be converted to a quotient ; 1 1/2 or 3/2 . Irrational number are those were the decimal goes to infinity and the decimal digits are in no particulr orderr. 'pi' is the classic axample at 3.141592.....

Is -3 an irrational or rational number?
If a number can be expressed as a terminating or repeating decimal then it is rational (and conversely). So -3 is rational.

Is 3.14 a whole number?
No. The '3' before the decimal point is a whole number. The '14' after the decimal point is a piece of a number.
Can a rational number have a decimal point?
Yes, for example 3/2 can be written as 1.5. All rational numbers have either a decimal expression of finite length or a repetitive pattern, unlike an irrational number, which goes on for ever when written in decimal form, never repeating.
What is the value of the number e?
Like pi the value of e is an irrational number and to 3 decimal places it is 2.718
What's the square root of 354?
It is an irrational number and it is about 18.815 rounded to 3 decimal places
