Abstract

This study aims to (1) Determine the types of errors students make in solving mathematical
problems in fraction material (2) Find out why students make mistakes in solving math
problems in fraction material. The method used in this research is descriptive method using
qualitative analysis. The research subjects were 24 students of class X IIS MAN Insan Cendekia
Sambas in the academic year 2019/2020. There are 24 students who take written tests and 7
students for interviews. The data in this study are data from test and interview results. Based
on this research, students' mistakes in solving mathematical problems in the material fractions
are (1) Incorrect in equating the denominator (2) Errors in simplifying the shape of numbers
(3) Correct in operating the steps, but wrong in writing the final result (4 ) Incorrectly changing
the shape of a fraction (5) Error in applying the properties of a fraction. The cause of student
errors is the inaccuracy of students in working on the problem of counting operations of
fractions, students lack of understanding of problems, lack of understanding of students in
using the properties of fractions, too hasty in working on problems, and students do not recheck the results of their work.
