Rational numbers: reduce absolute value

[mstranger]

Current tests do not consider the case, when a rational number can be reduced:

RationalNumbers.abs({2, 4}) = {2, 4}

Should the function abs in this exercise reduce a rational number?

Hi @mstranger,
That's an excellent question! Yes, every function should reduce the output number.
The best place to make that explicit however, is on the problem-specifications repo, like this recent PR for the same exercise. In this way, every track would benefit from the change.

Would you be willing to open a PR there?
It would be great to have a test that makes sure that the output is reduced for every function.

Thanks @jiegillet, I created a PR.

Nice, thank you!
I'll close the issue, please open a PR here with the new tests once that PR is merged :)
