Rational arithmetic functions are arithmetic functions of the form g1grh11hs1, where gi, hj are completely multiplicative functions and denotes the Dirichlet convolution. Four aspects of these functions are studied. First, some characterizations of such functions are established; second, possible Busche-Ramanujan-type identities are investigated; third, binomial-type identities are derived; and finally, properties of the Kesava Menon norm of such functions are proved.
