I think here applying voltage division rules this used only for resistors connected with voltage source if not then the converted number of resisters is only 2 resistor formate so,
If you find.
R0 =Vi* (R1/R1+R2).
R0=24* (68/68+68) =12.
If you find.
R0 =Vi* (R1/R1+R2).
R0=24* (68/68+68) =12.

We know voltage in one of the 68 ohm resistor is V=I.R1(R1=resistance of one of the resistors )
again V=(V/R).R1(R=total resistance of circuit.)
Hence,V=[24/(68+68)]*68=12V
Voltage divider rule is applicable for series circuit only because in series only voltage varies but not in paralel circuits.
again V=(V/R).R1(R=total resistance of circuit.)

24V is divided into two part each= 24/2 = 12V
