Answer:
Step-by-step explanation:
o convert your active-voice sentence (“Namrata is typing the letter now”) to the passive voice, change the direct object (“letter”) of the active sentence into the subject of the passive sentence. Change the subject (“Namrata”) of the active-voice sentence into the object of the preposition “by” in the passive-voice sentence. You must also change the verb a little and add the appropriate auxiliary verb (e.g., “is being”) plus the appropriate participle (e.g., “typed”).
The new, passive-voice sentence would be: “The letter is being typed by Namrata now.”
