Abstract: This study aims to describe students' mathematical communication skills in the material of ordinary and mixed fractions. The research subject is the seventh grade students of SMP Negeri 2 Nanga Pinoh and the object of this research is the students' mathematical communication skills. The type of research used in this research is descriptive qualitative research usingsurvey research methods. The instrument used is in the form of 3 test questions of mathematical communication skills in the form of descriptions. Research result obtained from the student's communication ability test showed that 43.5% of students answered according to the indicator of mathematical communication ability in writing and categorized as low and 63.05% of students answered according to the indicator of mathematical expression of communication ability and was categorized as moderate.
