This paper addresses a set-theoretic completeness based on a relational semantics for fuzzy extensions of two versions Rt and RT of R (Relevance logic). To this end, two fuzzy logics FRt and FRT as extensions of Rt and RT, respectively, and the relational semantics, so called Routley-Meyer semantics, for them are first recalled. Next, on the semantics completeness results are provided for them using a set-theoretic way.
