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.
If you divide an integer by another integer, the result is a rational number by definition.
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.
12 is the ratio of 12 and 1 ... nice and rational.

It is not an integer but is a rational number.
Some definitions maintain that the set of whole numbers does not include negative numbers. That makes -12 an integer and rational.

A rational number.
The number 12 is a natural number, a whole number, an integer, and a rational number. A natural number is a positive integer starting from 1, which includes 12. Whole numbers include all natural numbers along with zero, so 12 is also a whole number. Integers include all whole numbers along with their negatives, making 12 an integer. Lastly, a rational number is any number that can be expressed as a fraction, and 12 can be written as 12/1, making it a rational number.
