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.
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.
Yes and yes. It is an integer and so it is also a rational number.
6.3 is a rational number but it is not an integer because only whole numbers are integers.
-13 is rational and an integer.
Yes.
It is all three.
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.
Every integer is a rational number.
It is a rational number, not an integer.
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.
It is not an integer but is a rational number.
A rational number.
It can be written as a fraction, so it is rational. It is not an integer, whole number or irrational.
Zero is a rational number and an integer.
A rational number is either an integer or a fraction.
-23 is rational.It is rational because we can write it as a fraction (one integer divided by another) where the denominator is not equal to 0. For example, -23/1. This makes it rational.
