clock hands snark busters.. i'm ita

on the sign are the following times: 3:00,8:25 (with a sign), 5:15,4:15. how do I set the clock? whom he describes all the steps to set the time? I'm Italian .. can you help me

set the times, one after the other - the hands have to be right on the numbers, not between numbers like they would really be.

I have a different problem, since my sign says 8:55, 6:50, 3:50, :20...?
Not sure how to show 20 minutes?
