 """ Converts mixing ratio x in c1 - c2 tie line to that in comp1 - comp2 tie line. Args: x (float):
 Mixing ratio x in c1 - c2 tie line, a float between 0 and 1. factor1 (float):
 Compositional ratio between composition c1 and processed composition comp1. E.g., factor for Composition('SiO2') and Composition('O') is 2. factor2 (float):
 Compositional ratio between composition c2 and processed composition comp2. Returns: Mixing ratio in comp1 - comp2 tie line, a float between 0 and 1. """

        return x * factor1 / ((1-x) * factor2 + x * factor1)
