Abstract: 
In this paper, we confirm the existence of three positive solutions for a class of RiemannLiouville fractional $q$difference equation which satisfies the boundary conditions. We gain several sufficient conditions for the existence of three positive solutions of this boundary value problem by applying the LeggettWilliams fixed point theorem.
