[Decimals and Fractions]: Refine Concepts and Consider Adapting the Related Exercise from Julia

[BethanyG]

See discussion & proposed exercise here.

See related concept write-up:

• Fractions

We would need to also complete a Decimals concept and related concept exercise.
We might also want to contemplate more than one Fractions exercise, since the strategy of making and using Fractions changes when you need to inter-operate with other numeric types, or make fractions out of floating point numbers.

@colinleach - I would have assigned you, but I can't seem to do that unless you are already on the thread.

That sounds like a pretty strong hint!

Just sayin' 😉 Feel free to say "hell, no!". Won't be offended. Also? Absolutely no rush on this or obligation. Just wanted a space for discussion that didn't pollute the Julia PR with excessive or off-track noise! ❤ 😄

Participating in the discussion does not obligate you to PR or do more work. Seriously.
