### Abstract

The purpose of this study is to describe mathematics representation of vocational high school students in
solving linear program problem. The representation that will be seen is pictorial representation, symbolic
representation and verbal representation of students with varying abilities. The research subjects were 3
students of class XII from one of the Vocational High Schools in Jambi with a variety of high, medium
and low ability levels. The data was collected by giving two linear program problems that the students
would work on, then conducting interviews based on each student's answer sheet to strengthen the test
result data. Answer sheet data and interview results were analyzed and presented in narrative text.
Students with high abilities implement the three forms of representation accurately and are able to change
the form of one representation to another representation. Students with moderate abilities do not
implement pictorial representation and symbolic representation accurately. Low ability students do not
implement pictorial representation in problem solving.
