120 / 6 = 20 Ohms
(Note: This simplified version of the "parallel resistor" formula only works if they are all the same value.)

If you meant that there are 6 separate but equal 120 ohm resistors in parallel, then the answer is 20 ohm via the method of the first answer. If you mean that there is a 6 ohm resistor in parallel with a 120 ohm resistor then the answer, by the same formula (1/Rt= 1/6 + 1/120) is 5.714 ohm.

six identical 120 ohm resistors in parallel?
1/R = 6 * (1/120) = 6/120 = 1/20
R = 20 ohm.

(1 ÷ 120) x 6 = 0.05
1 ÷ 0.05 = 20 Ω Total resistance.

1/R = 1/6120 + 1/6120 +1 /6120
= 3/6120
R = 6120/3 = 2040 ohms

Rt = 1/ {(1/r1) + (1/r2) + (1/r3) + (1/r4) + (1/r5) + (1/r6)}
Rt = 1 / {(1/120ohms) + (1/120ohms) + (1/120ohms).........}
Rt = 1 / (6/120ohms)
Rt = 1 / (1/20ohms)
Rt = 20 ohms
