In this paper, we have tried to clearly explain the meaning of fractions and operations with fractions. Also, we have tried to illustrate with some examples how to apply the rules of operations with fractional numbers, giving different practical techniques through different figures, visualization methods, and concretizing problems. The paper presents with examples of the most common mistakes made by students, giving suggestions for their avoidance, as well as through a questionnaire, which considered the survey of 60 students of grade 6 of school, "Elena Gjika" City Prishtina, Kosovo, with the help of the statistical test we have concluded that practical techniques such as figures, visualizations, and video lessons have a close dependence on the meaning and operation of fractions.
