This paper introduces a multiplicative analogue of the Bullen quadrature rule and develops a suitable notion of convexity tailored to the $ G $-calculus framework. Building on these foundations, we derive a new fractional identity in the multiplicative setting, which serves as a key enabler for establishing Bullen-type inequalities via multiplicative Riemann-Liouville fractional integrals. This work integrate fractional calculus with multiplicative analysis for the study of integral inequalities, thereby proposing a novel pathway within non-Newtonian mathematical systems. Our results advance the theory of generalized calculus and open promising directions for future investigations into multiplicative fractional inequalities.
