学习数学的目的是为了应用,是为了解决生活中的实际问题。应用题是初中阶段的一类重要的题型,也是学生感觉比较难而又怕的一类问题.列分式方程解应用题是中考重点考查的内容,然而因为其中牵涉的量比较多,学生往往整理起来很是吃力。将这类问题结合表格法总结为好记的“三二一”法则,使得这个难点得以突破。 The purpose of learning mathematics is to apply, in order to solve practical problems in life. Application problem is an important type of junior high school questions, but also students feel more difficult and afraid of a class of problems. Classification of equations is the application of the key points in the exam test content, but because of the more involved in the amount of students Often it is difficult to sort it out. The combination of such problems with the tabular approach is a good guide to the “321” rule, making this difficult breakthrough.
