In this paper, with a new approach, a new Hermite-Hadamard-Fejér inequalities without symmetry condition for convex functions is obtained by using not only Riemann integrals but also the Riemann-Liouville fractional integral. Also, to have new fractional trapezoid and midpoint type inequalities for the differentiable convex functions, some new equalities are proved. Additionally, we will provide some examples of special cases that arise from these inequalities.
