Passive to Active
Reverse the process: find the doer (after 'by'), make it the subject, drop the 'be' helper, and use the correct active verb form in the same tense. If no doer is named, supply a sensible subject.
Run the swap backwards
- Find the doer (the word after "by") and make it the subject.
- Drop the "be" helper; use the active verb in the same tense.
- Move the old subject to the object position.
"A letter is written by Ram" → doer "Ram" becomes subject → "Ram writes a letter".
