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.
