Explanation:
Passive voice is described as the grammatical construction in which the object and the action stated by the verb are emphasized rather than the subject. The subject in such construction becomes the recipient of the action and is acted upon(by the verb). It helps in showing interest in the noun(in object place) which undergoes the action instead of the doer(subject) who performs it.
In order to convert the given sentences from the active voice to the passive voice, the object will be substituted with the subject in order to shift the emphasis. Since the subject is the recipient of the action, it can be omitted or written using 'by' as mentioned above.
