Proof step 15 from proof mod-div-ls (previous step)

i1 ≤ (i1 * (j0 + 1)) / j, j0 < j, 0 < j, 0 < i1, 0 ≤ i0, i1 ≤ (i0 + i1 * j0) / j, i0 < i1, 0 ≤ j0, 0 ≤ i2, i0 < (i0 + i1 * j0) / j, 0 < (i0 + i1 * j0) / j ⊦ j0 + 1 = j

And obtained the following new goals

Proof step 16:
i1 ≤ (i1 * (j0 + 1)) / j, j0 < j, 0 < j, 0 < i1, 0 ≤ i0, i1 ≤ (i0 + i1 * j0) / j, i0 < i1, 0 ≤ j0, 0 ≤ i2, i0 < (i0 + i1 * j0) / j, 0 < (i0 + i1 * j0) / j ⊦ (i1 * (j0 + 1)) / j < i1, j0 + 1 = j

Rule argument

fma: (i1 * (j0 + 1)) / j < i1

Additional information

Used simplifier rules: lenls: ⊦ i ≤ j → ¬ j < i; from specification int-abs Used formulas: (i1 * (j0 + 1)) / j < i1
