2) 1 2 3 for everything underneath
3) 3/4 and the same
A quarter note gets 1 beat. Think of a dollar, but this is 3/4 and you only need 75 cents for something. A dotted note adds 1/2 of the original value to the note. So a dotted quarter note would be one and a half beat, or the equivalent of a quarter note and an eight note.
