Whatever the teacher in your class is using, I suppose.
As far as I know, there is no standard meaning to "simplifying". In general, it refers to "reducing". In the lower grades, it often also refers to "converting improper fractions to mixed number", because that is, for some reason, often the preference at that level of study. This extra step is dropped, or even actively discouraged, in higher-level study.
