###### Wiki User

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

### 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.

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.

### Can the quotient of two irrational numbers be rational?

Yes. 2*pi is irrational, pi is irrational, but their quotient is 2pi/pi = 2: not only rational, but integer.

### Is pi over 12 a rational number?

No. To be a rational number it must be an integer over another integer. &pi; is not an integer, nor can it be made into an integer by multiplying it by another integer, thus one twelfth of &pi; is not a rational number.

### Is 22 over 7 a rational number?

Yes. A rational number is defined as any integer divided by any (nonzero) integer, so 22/7 is rational.You're probably asking because some people say that Pi is equal to 22/7 (I also remember being told this once as a kid). This is false. The constant Pi is an irrational number, which means that it cannot be expressed exactly as one integer divided by another integer, or as a finite decimal expansion. 22/7 is a close approximation of Pi, to about three digits, but it does not equal Pi.

### What is a negative none integer?

A negative number that is not an integer, of course. Examples are minus 1.5, minus pi, minus square root of 2, etc.

### What are the two closest integers for each irrational number?

They are the integer part of the irrational number and the successor to that integer. Thus, for pi, the two integers are 3 and 4.

### Where is trigonometric function in negative?

In the domain [0, 2*pi],sin is negative for pi cos is negative pi/2 tan is negative for pi/2 Also, the same applies for all intervals obtained by adding any integer multiple of 2*pi to the bounds.

### Why negative pi is a negative rational number that is not an integer?

The question cannot be answered because it is based on a false premise: negative pi is NOT a negative rational number.
