Try Qalculate!.
It’s not a scientific calculator, but I had a TI-Nspire in college. That thing could do fractions with variables in them. It was really nice.
I have a whole Linux machine with a bunch of displays, 16 cores, tons of memory, powerful GPU, and an internet connection. And I still have a TI-84Plus sitting on my desk which I use for all my calculator needs… It’s just easier.
Yeah. Most of the graphing calculators that have a built-in CAS (computer algebra system) can show results that way. Prob what OP is looking for.
I’m way out of date, but I had a TI-89 that had that feature.
ages ago I used various Hp (and other) calculator emulators for some tasks I needed to do.
they had more features than any of the calculator programs I had checked out.
But that was many many years ago.
also saw some options mentioned here.

I would try pari/gp, I’m pretty sure it does Dec to frac… Also python has a numeric library I’ve used for that before, although its a bit more complicated than using a calculator like system

Automatically puts answers in fractions, but has a button to switch between the two as well. Can also have fractional input. Not sure what model is current though, this one is pretty old.
This is the Linux community.
I barely use a calculator, but you could try SageMath if you like the thought of writing you math in Python.
