  1. just use the formula:

    1/R = 1/10 + 1/20 + 1/60

    The voltage does not matter. The formula works because each resistor allows a current to pass, and the currents add up to the total.

    Since E=IR, I=E/R, and you have a total current of

    12/10 + 12/20 + 12/60

    That current is the total current I, and R=12/I. That is, I=12/R, the total resistance.
