Final answer:
Ethan's errors in the book of accounts match with different types of accounting errors: original entry, transposition, reversal of entries, calculation, and omission.

- Transposition error: Ethan records stationery expenses as $251, but it should have been $215.
- Reversal of entries: Ethan records salaries of $5,000 as credits instead of debits.

- Omission error: Ethan completely overlooked stationery expenses of $115.
