列方程解浓度问题作为分数、百分数问题的实际应用题,不仅在工农业生产中经常碰到且在以后学习等比数列、指数方程等课程也常涉及。学生对理解和掌握这部分内容历来都比较困难,是初一数学难点之一。现谈谈我对突破这一难点的一些做法和体会。 The equation solution concentration problem is used as the practical application of fractions and percentages. It is not only encountered frequently in industrial and agricultural production but also later studied in the course of equal numbers and exponential equations. Students have always been difficult to understand and master this part of the content, and it is one of the difficulties of mathematics in the first year. Let me now talk about some of my practices and experiences in breaking this difficult point.
