In a parallel circuit, the total circuit current equals the sum of the individual currents.

A parallel circuit contains standard lamp of $\displaystyle \frac{{2}}{{15}}$ amps, lava lamp of $\displaystyle \frac{{1}}{{9}}$ amps, and a radio with $\displaystyle \frac{{2}}{{5}}$ amps. Determine the total current of the parallel circuit.

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