Summary:Fraction is one of the subject that begins to be studied in primary school and often found in daily life. Therefore, students, especially in seventh-grade are familiar with the subject. The purpose of this study is to explore information and describe students' error in solving fraction problem. The research method used is descriptive research. The subject of this study were 30 seventh-grade students at SMP Negeri 1 Piyungan. The research instrument used is the test containing fraction problem. The result showed that students still made mistakes in solving the fraction problem. First, students are wrong in rewriting the known components of the problem. Second, they are wrong to apply the concept of fractional counting operations. Third, they are wrong to convert mixed fractions into ordinary fractions and vice versa. Fourth, they are wrong to change integers to fractions. Fifth, they are less careful in performing a fractional counting operation. Lastly, they are wrong to sort fraction number.
