No, all terminal decimals are rational numbers. For a number to be irrational, its decimal representation must be non-terminal (never end) and never repeat. Here are a few terminal decimals and their fractional equivalents. Note that any number which can be expressed as any ratio of integers is rational.
0.333 = 333/1000
0.4 = 4/10 = 2/5
0.1427 = 1427/10000
In general, any terminating decimal expression has a certain number of digits after the decimal point. We will call those digits D1, D2, D3, D4, ... DN. We will ignore the whole-integer part of the number as this is rational and any rational number combined with another rational number is rational. The non-integer part (fractional-part) of this number can be expressed as the ratio:
(D1D2D3...DN)/(10N)
The numerator is an integer because all of the Dxs are integers from 0 to 9 inclusive. The denominator is an integer because N is the number of digits after the decimal in the terminal decimal expression, and 10 to a finite, integer power is an integer. Thus, any terminating decimal can be expressed as a ratio of two integers and is thus rational (not irrational).

Are natural numbers irrational numbers?
No. All natural numbers are whole, so they are rational. Irrational numbers like pi and the square root of 34 come in decimals.
What is the phobia of repeating decimals called?

What are two characteristics of a rational and irrational number?
Rational numbers - can be expressed as a fraction, and can be terminating and repeating decimals. Irrational numbers - can't be turned into fractions, and are non-repeating and non-terminating. (like pi)
Are repeating decimals rational?
Yes. Rational numbers are numbers or decimals that repeat or terminate. Irrational numbers do not. For example π is an irrational number.
Are recurring decimals considered irrational numbers?

Are all integer irrational numbers?
No integers are irrational numbers. An integer is a whole number, positive or negative. This means they have no decimals or fractions. An irrational number, however, is a number with fractions or decimals. Therefor, there are no integers that are irrational numbers.
What do you called the set of infinite decimals and non perfect square root?
Infinite decimals: irrational numbers; Non-perfect square roots: a subset of irrational numbers.
