In this paper, an approximate solution for solving nonlinear mixed Volterra-Fredholm fractional integro-differential equations is presented. The fractional derivative is defined in terms of Caputo type. Two methods are suggested: Adomin Decomposition Method (ADM) and Residual Power Series Method (RPSM). In these methods, Adomian polynomials and residual function are derived. The fractional Volterra-Fredholm integro-differential equation is reduced to a recurrence formula, in which it can be solved rather straightforward. Numerical examples demonstrate the efficiency and accuracy of ADM over RPSM.
