Question

open all the windows
into passive voice​

Answer 1

Answer:

imperative sentence

you are ordered open all the windows.

Answer 2

Let the windows be opened.

Explanation:

• The given question is in active voice and has to be converted to passive voice. The given sentence is an imperative sentence, therefore, we have to use "let" as the sentence depicts an order.
• We could have used that "someone ordered to open the windows" but here the given sentence does not speak about the speaker so we should not add it on our own when we can work it out without adding it.
