Abstract: This paper deals with  a minmax fractional problems in terms of the right derivative of the function with respect to an arc.  Under arcwise connected type I and
generalized arcwise connected type I assumptions, a dual model is proposed for the minmax fractional problems. Furthermore, weak duality theorem, strong duality theorem and strict converse duality theorem are established.
