Question

change the sentence into passive form I was signing a song​

Answer 1

$\huge\bold\underline{Active - Passive}}}$

A song was being sung by me.

Few Rules :

⭐ In active voice the format is like :

Subject - Verb - Object.

When a sentence is turned to passive voice the formal will be like :

Object - Verb - Subject.

⭐ We observe that the place of the object and the subject is interchanged in the above format when a sentence is turned to passive voice.

Note :

✴ Verb be changed to 3rd form.
