There is one 1/4 of a beat in a sixteenth note, if a quarter note gets one beat. This is not true for all signatures.
The value of the beats doubles or halves.
Whole note = 4 beats (half of 4 is 2)
half note = 2 beats (half of 2 is 1)
quarter note = 1 beat ( half of 1 is 1/2)
8th note = 1/2 beat ( half of 1/2 is 1/4)
16th note = 1/4 beat ( half of 1/4 is 1/8)
32nd note = 1/8
The clue is in the name of the note. The sixteenth (or semiquaver) is one-sixteenth of a whole note (or semibreve). Look at the time signature of your piece of music: a semiquaver rest will occupy exactly the same number of beats as a semiquaver note. For example, if your piece is in 4/4 time, it will occupy a quarter of a beat.
In 3/4 time (whether you are playing a piano or a kazoo), there are 3 beats to the measure and a quarter note gets one beat. There are four sixteenth notes to a quarter note so the sixteenth note gets 1/4 of a beat or, another way to look at it is it takes 4 sixteenths to make a beat.
If it is 4/4 time, then it gets 1/4 of that quarter note. So meaning there would be 16 sixteenth notes in a measure if you filled the bar with sixteenth notes.
A sixteenth note lasts for one-fourth the duration of a quarter note. In a 4/4 time signature, where there are four beats per measure, a sixteenth note occupies one-sixteenth of a measure. This means that four sixteenth notes can be played in the time it takes to play one quarter note.
2 sixteenth note
A sixteenth note receives 1/4 of a beat. It is referred to as a "sixteenth note" because it takes sixteen of them to create 4 beats. Most songs contain 4 beat measures known as "common time."

2 sixteenth note
A semiquaver or a sixteenth note takes 1/4 beats according to the common convention that a quarter note takes one beat.
Twelve. Remember that the dot always adds one half of the original note to the total - so a dotted half note is three beats in length. (Cut a half note in half and you get a quarter, so a dotted half note is two beats for the half note and one beat for the quarter you added to it) So now you can take those three beats (Three quarter notes) and cut them in half, which is six eighth notes, and then cut that in half and get twelve sixteenth notes. Phew. I hope that made sense.
I think it's 28 -- there are four sixteenth notes in one quarter note times seven beats in the measure. However, I've never heard of a time signature with seven beats, so it's probably not very relevant. Also, this answer assumes each beat is a quarter note (not, say, a dotted quarter or an eight).
A dotted quaver (dotted eighth note) is worth 1.5 beats, while a semi quaver (sixteenth note) is worth 0.25 beats. When you add them together, a dotted quaver plus a semi quaver equals 1.5 + 0.25, which totals 1.75 beats.
A whole note is worth 4 beats, a half note is worth 2 beats, a quarter note is worth 1 beat, an eighth note is worth 1/2 a beat, a sixteenth note is worth 1/4 of a beat, a dotted half note is worth 3 beats, and a dotted quarter note is worth 1 and a 1/2 beats.
A quaver with two tails is a musical note known as a "demisemiquaver" or "sixteenth note." It is worth one-sixteenth of a whole note in terms of duration. In terms of beats, it typically receives half a beat in common time (4/4).
