The current work deals with the fractional forms of EW and modified EW equations in the conformable sense and their exact solutions. In this respect, by utilizing a traveling wave transformation, the governing space-time fractional models are converted to the nonlinear ordinary differential equations (NLODEs); and then, the resulting NLODEs are solved through an effective method called the exp(-phi(epsilon))-expansion method. As a consequence, a number of exact solutions to the fractional forms of EW and modified EW equations are generated.
