Integer numbers are numbers which have no fractional part, such as ...,-2, -1, 0, 1, 2,...
Rational numbers are numbers which can be expressed as a ratio or fraction (e.g. 1/5, 1/3, 1/2, 0.05, etc.)
Irrational Numbers are numbers such as PI which cannot be accurately represented by a fraction. These are also sometimes called "non-repeating decimals". By definition an irrational number has an infinite number of "significant" digits to the right of the decimal point. (Any number with a finite number of significant digits can be expressed as a simple fraction, e.g. 0.01 = 1/100, 3.142857 = 22/7 which is a commonly used approximation for the irrational number pi which begins 3.14159...)
It is an integer. All integers are rational but not irrational. All rational and irrational numbers are real numbers.
No integer is an irrational number; all integers are rational.
It is real, rational, integer and whole but not irrational nor counting.
It is rational, whole, integer and real but not natural nor irrational.
Irrational. The square root of a positive integer is either an integer (that is, if the integer is a perfect square), or an irrational number.
It is an integer. All integers are rational but not irrational. All rational and irrational numbers are real numbers.
It can be written as a fraction, so it is rational. It is not an integer, whole number or irrational.
