Do you mean, how do you turn a sentence from the active to the passive? In all cases, the former object of the sentence becomes the subject. The verb form also changes, as follows, using the verb to take as an example:
Infinitive: to take becomes to be taken
Future: will take becomes will be taken
Present: take becomes is taken
Progressive: is taking becomes is being taken
Past: took becomes was taken
Past Progressive: was taking becomes was being taken
Imperfect: have taken becomes have been taken
Pluperfect: had taken becomes had been taken
E.g.
The Prime Minister will steal the treasury. = The treasury will be stolen
The Prime Minister is stealing the treasury. = The treasury is being stolen.
The Prime Minister stole the treasury = The treasury was stolen.
The Prime Minister was stealing the treasury = The treasury was being stolen.
The Prime Minister has stolen the treasury = The treasury has been stolen
You will note that using the passive voice enables you to describe the action without actualy saying who the actor is. This is great if you happen to be one of the Prime Minister's spin doctors, for example.
The passive voice of ''what do you do'' is "what is done by you?"
"Your name is not known by me." is passive voice.
"Will you marry me" can be changed to passive voice as "Will I be married by you." In the passive voice sentence, the subject of the active voice becomes the object of the passive voice, and the object of the active voice becomes the subject of the passive voice.

Can it be changed into passive voice?
passive active A+
To write in passive voice, you put the actor (subject) second. Active - Sammy made tea. Passive - The tea was made by Sammy. Passive voice often has the word by before the actor. Note: Instead of I made tea, you would need to write, "The tea was made by me." About how to make tea, think about the precise steps to make tea. Put these in chronological order. Write about each step, but in passive voice.
Yes it is passive voice.
No this sentence is not passive voice.
It is passive voice.
No, by including the subject 'I' you have avoided the use of the passive voice. Passive voice would be. 'It was missed.'
