The fraction 1/3 is a compact and unambiguous representation—it doesn’t rely on an ellipsis or an understanding of infinite series to be interpreted. It can easily be used in later calculations (you never see … notation in algebra). It is a useful notation.
As soon as you use decimals in computer and human calculations, they become lossy.
I’m not really sure what hill you are trying to die on. Fractions are useful, even if you don’t know how to use them.
So you think
0.333.... + 0.333.... + 0.333.... = 1
Is clearer and more concise than
1/3 + 1/3 + 1/3 = 1
Fractional representation is the method for rational numbers, particularly if they are part of an intermediate calculation.
Decimals are lossy, fractions aren’t.
No because you said this:
You can also precisely write to infinity if you write 0.333…
Decimals aren’t lossy, any fraction can be converted to decimal but it just takes longer to write.

What does lossy mean? I’m not trying to die on any hill, but I’m quite confused aswell.
