Abstract The quotient field of the ring of invariants of a rational Ga action on C n is shown to be ruled. As a consequence, all rational Ga actions on C4 are rationally triangulable. Moreover, if an arbitrary rational Ga action on C n is doubled to an action of Ga × Ga on C2n, then the doubled action is rationally triangulable.
