Answer 2

Answer:

The students have decorated the hall beautifully : Change into Passive Voice

• The passive voice is : The hall has been decorated beautifully by the students.

• The given sentence is an example of Present Perfect Tense.

• Voce Change is done according to Tense.

• So the structure of Present Perfect Tense is : object of Active Voice as subject + auxiliary verbs ( have / has ) + been + main verb's 3rd form + object + preposition ( by / with according to subject) + subject of active voice or objective case of Pronouns.

• Here 'the hall' is a Singular Number. That's why 'has' has been used as Helping Verb.

• Example : He has made a doll ( Active ). A doll has been made by him (Passive).
