pi, e
Irrational Numbers have names because they cannot be written down completely. Pi (as in Pi R squared) and e ( Euler's number, a mathematical constant) are examples of irrational numbers.
Another answer:
Irrational numbers are numbers that cannot be stated as the quotient of two integers. The square root of 2, 1.414..., is an example to an irrational number. Pi and e are transcendental numbers, where they cannot be expressed as the root of algebraic equation having integral coefficients.

it is not irrational. This is because there are two non irrational numbers that divide each other that are rational. So 10.46 is rational.
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)
Integers are whole numbers. They are the counting numbers, 0 and the corresponding negative numbers. Rational numbers are numbers that can be expressed as a ratio of two integers (the second one being non-zero). Irrational numbers are numbers that are not rational numbers. Rational and irrational number together form the set of real numbers.
If they are non-terminating and there is a repeating pattern, then they are rational. If they are non-terminating and there is no repeating pattern, as in pi, they are irrational.
It terminates. I believe that numbers that are non terminating are irrational. and numbers that can be made into a fraction, terminat, or repeat are rational.
