Proof step 22 from proof denom-neg-02 (previous step)

0 < 1 ∧ 0 < j, gcd(i, j) = 1, 0 < j ⊦ rational(~ i, j).denom = j

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 23:
⊦ rational(~ i, j).denom = rational(i, j).denom

Rule argument

name: denom-neg-01 rotate: F subst: [j, i] → [j, i]

Additional information

Used simplifier rules: denom-id: ⊦ gcd(i, j) = 1 ∧ 0 < j → rational(i, j).denom = j; Used terms: j, i
