An ideal transformer scales voltage by a checked turns ratio. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
A turns ratio is a voltage scale
The primary side is fixed at 6 turns and 24 V. Only the secondary turns are allowed to move in the scan.
VpVs=NpNs
The secondary voltage moves with secondary turns
The three rows keep the same primary side, so each secondary voltage is just the turns fraction times the source.

The secondary voltage is fixed by the turns ratio
The ideal transformer has 6 primary turns and 2 secondary turns, so the voltage scale is checked before any load claim.
