In a parallel circuit, the total resistance is defined as

$\displaystyle {R}{T}=\frac{{1}}{{\frac{{1}}{{{R}{1}}}+\frac{{1}}{{{R}{2}}}}}$ where R1 and R2 are readings of two resistors.

Find the total resistance of a circuit with two resistors of $\displaystyle {1}$ ohms and $\displaystyle {6}$ ohms.

Give your answer as a fraction, reduced to lowest terms. No need to enter "ohms".
