This article presents the results of an investigation whose research question was: Can students who correctly choose operations in questions involving natural numbers have the same ability in questions involving decimal numbers in questions of the multiplicative field? Faced with this question, the objective of the study was to investigate how the percentage of correct choice of the operation behaves in multiplicative questions with decimal numbers when there is the correct choice of the operation in multiplicative questions with natural numbers. The production of information took place through a test applied to 109 students from five classes of three public schools located in the city of Confresa, in the state of Mato Grosso, Brazil. The test contained multiplicative questions involving natural numbers and decimal numbers with similar structures, divided into arithmetic and algebraic questions. The data obtained by the tests composed of arithmetic multiplicative questions and algebraic multiplicative questions with natural numbers and decimal numbers indicated high percentages of correctness in the choice of operation in multiplicative questions involving decimal numbers when the choice of the operation in multiplicative questions involving natural numbers occurred. In addition, it was possible to notice that the students' performance in multiplicative arithmetic questions was better in relation to solving algebraic questions.
