Proof step 2 from proof mult-02 (previous step)

i0 < j, 0 < j0, 0 ≤ i0, 0 ≤ i ⊦ (i * j + i0) / (j0 * j) = i / j0

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
0 < j0, i0 < j, 0 < j, 0 ≤ i, 0 ≤ i0 ⊦ (i * j + i0) / (j0 * j) = i / j0

Rule argument
