What are some examples of a fraction but not a rational number?
A rational number is a fraction with an integer in the numerator, and a non-zero integer in the denominator. If you consider pi/2, pi/3, pi/4 (common 'fractions' of pi used in trigonometry) to be 'fractions', then these are not rational numbers.
Is 3.14 an irrational number a rational number or an integer?
3.14 is rational. However, it is often used as an approximation for pi, which is irrational.
Is pi over 2 a whole integer rational or irrational number?
If you multiply or divide an irrational number - such as pi - by ANY rational number (except zero), you will ALWAYS get an irrational number.
Is negative 5 pie a rational number?
No, and nor is negative 5 pi.
Pi is a fraction as circumference by diameter p by q form is a rational number then how is pi a irrational number?
A number is said to be rational if it can be expressed as a ratio of two [finite] integers [the second of which is non-zero]. Here, if pi is to be rational, both p and q must be integers. If p is an integer then q will be irrational and if q is an integer, p will be irrational. They can never both be rational and so the ratio definition cannot be satisfied.
What is a negative rational number?
Minus two.Some rational numbers are positive, some are negative. -9 is a negative rational number.
Is pi over 12 a rational number?
No. To be a rational number it must be an integer over another integer. π is not an integer, nor can it be made into an integer by multiplying it by another integer, thus one twelfth of π is not a rational number.

Is pi an integer?
pi is not a integer any of the natural numbers (positive or negative) or zero; "an integer is a number that is not a fraction"- since pi has a decimal it isn't considered a integer
Is 3.14 an irrational number a rational number or an integer?
3.14 is rational. However, it is often used as an approximation for pi, which is irrational.
Is pi over 2 a whole integer rational or irrational number?
If you multiply or divide an irrational number - such as pi - by ANY rational number (except zero), you will ALWAYS get an irrational number.
Is negative 4.9 a rational or irrational?
-4.9 is a rational number. If a number is irrational, then it can not be expressed as a finite number of digits. A few examples of irrational numbers are: pi, the square root of any integer which is not square and the golden ratio (phi).
What is an example of a rational number an integer and a real number?
1/2, 5, pi, respectively
Is negative 5 pie a rational number?
No, and nor is negative 5 pi.
What number that is a negative but not integer?
-1.5, -pi, -2/5

Is pi irrational rational complex or an integer?
pi is real, irrational and transcendent; it is not rational, complex, nor an integer.Yes, it is non-terminating and non-repeating.Yes, pie is an irrational number.
