In this paper, we find real roots for fuzzy polynomial equations (if exists) by ranking fuzzy numbers. We transform fuzzy polynomial equation to system of crisp polynomial equations, this transformation perform with ranking method based on three parameters Value, Ambiguity and Fuzziness. Provided system of crisp polynomial equations can be solved numerically. Finally, we illustrate our approach by numerical examples.
