Equivalent resistance of the three resistor
= (2200 + 820 + 8200) Ω
= 11220 Ω

Voltage across R1
= 16.1 × (2200/11220) V
= 3.16 V

Voltage across R2
= 16.1 × (820/11220) V
= 1.18 V

Voltage across R3
= 16.1 × (8200/11220) V
= 11.8 V

That's pretty basic.  You need to get your head around what resistance means.  Hint: The same current flows through all three resistors.
