Proof step 5 from proof mult-zero (previous step)

⊦ rational(0, ri.denom) = rational(0, 1)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ rational(0, j) = rational(0, 1)

Rule argument

name: zero-num rotate: F subst: [j] → [ri.denom]

Additional information

Used terms: ri.denom
