It is a rational fraction.
Not quite. A rational number is a ratio and each rational number is a ratio of specific pairs of integers - not ANY two integers. And, of course, 0 is not allowed on the denominator.
121 can be expressed as the ratio 121/1, where both numerator and denominator are integers, the denominator not being 0. That is the definition of a rational number.
And the denominator is 0

The ratio of two integers is a fraction that represents the division of one integer by another. As long as the denominator is not equal to zero, the ratio is defined. For example, the ratio of 4 to 2 is 4/2, which simplifies to 2.
