Question

Answer 1

Ответ:

Did he brush his teeth at 6 a.m. yesterday?

Answer 2

Did he brush his teeth at 6:00 in the morning yesterday?

Answer 3

Yesterday, did he clean his teeth at 6:00 in the morning?

In English, when forming a question, we usually use the auxiliary verb "did" before the subject and follow it with the base form of the main verb. In this case, the main verb is "clean," so the question would be: "Did he clean his teeth at 6:00 in the morning?"
