用数学的观点来看,客观世界的事物都可以用数量关系来表示。所谓数量关系就是指事物与事物之间的量与量、数与数之间存在的联系和相依关系。这种关系表现在每一道应用题中。在应用题教学中,常见的数量关系有哪些内容呢?弄清这个问题,有利于我们引导学生分析应用题和解答应用题。在应用题中常见的数量关系有:1.多和少的关系。也就是同类量之间比较大小的关系。例如,反映同类量的两个数经常存在着甲比乙多或乙比甲少这样的关系。又称“差比”关系。表现在应用题中是:
From a mathematical point of view, things in the objective world can be expressed in quantitative terms. The so-called quantitative relationship refers to the relationship between the amount and quantity of things and things, between the number and the number and the relationship between. This relationship is reflected in every application question. In the application of teaching problems, what is the relationship between the number of common? Clear understanding of this problem, help us to guide students to analyze and answer questions. In the application of the number of common questions are: 1. More and less relationship. That is, the relationship between similar sizes. For example, the two numbers that reflect the same kind of quantity often have the relationship of more or less than one. Also known as “bad ratio” relationship. Performance in the application title is:
