Proof step 9 from proof zero-denom (previous step)

i ≠ 0 ∧ 0 < 1, i ≠ 0 ⊦ i = i / 1 ∧ rational(i, 0).denom = rational(i, 1).denom

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 10:
⊦ i ≠ 0 → rational(i, 0).denom = 1
Proof step 11:
i ≠ 0, i ≠ 0 ∧ 0 < 1, i ≠ 0 ⊦ i = i / 1 ∧ 1 = rational(i, 1).denom

Rule argument
