A rational number which is an integer can be simplified to a form in which the denominator is 1. That is not possible for a rational number which is not an integer.
A rational number is always the result of dividing an integer when the divisor is nonzero.
An integer is any number which can be either positive and negative but not a fractional number. It is also a whole number. Examples are -1,256, -589, -1, 0, 1, 569, 5,236. It is always a rational number. By definition, a rational number is the division of two integers, where the divisor is not zero. Since the divisor is 1 when the number is an integer, then all integers are rational.
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.
The answer depends on what an "interfer" is.
Yes, always. That is the definition of a rational number.
Because that is how a rational number is defined!
2/3 is a rational number but not an integer.
Yes, integers are always rational.
Yes, that is how a rational number is defined.
Yes, by definition!
Yes, it is.
It is a rational number, not an integer.
Every integer is a rational number.
