The field of synthesis and practice is a type of learning activities that takes the problem as the carrier and the students take the initiative to participate. It is an important way to help students accumulate experience in math activities and cultivate students’ awareness of application and innovation. In view of the problem situation, the students synthesize the knowledge and life experiences they learned, think independently or cooperate with others, experience the whole process of discovering and asking questions, analyzing and solving problems, and realize the relationship between the contents of mathematics and the reality of mathematics and life Between mathematics and other disciplines, deepen the understanding of the mathematical content. Based on this, the day before the National Day Friday, finished “fractional multiplication ” This part of the knowledge
