“…related to ratio and proportion). Ratio is a situation in terms of comparison (Dole et al, 2012), in which it can be written in the form of 𝑎 𝑏 or 𝑎 ∶ 𝑏 that expresses a multiplicative relationship between two quantities (Keersmaeker et al, 2023). While, proportion is a statement of equality of two ratios that can be expressed in (Tourniaire & Pulos, 1985;Prayitno et al, 2018).…”

The purpose of this study was to analyze students' proportional reasoning ability. The research subjects consisted of 21 students of VIII class in one of the public junior high schools in Semarang City who had obtained comparison materials (ratio and proportion). Data collection used test instruments that were developed based on indicators of proportional reasoning ability consisting of 6 questions. The data were analyzed qualitatively with data reduction analysis procedures, data presentation, and conclusion drawing/verification. The results showed that (1) none of the students met all the indicators of proportional reasoning ability, namely the ability to understand proportional relationships, solve proportional problems of missing values, numerical comparisons, qualitative predictions, distinguish proportional and non-proportional problems, and solve proportional relationships of inverse values, (2) all students have been able to understand proportional relationships, but they are still very limited in their ability to distinguish proportional and non-proportional problems, and solve proportional relationships of inverse value, and (3) the strategy most often used by students to solve proportional reasoning problems is the cross-multiplication strategy.
