分式方程应用题一直是中考的考点,解答这类问题要仔细审题,认真分析,关键是找出题中的基本关系式。 一、工作效率问题 例1 甲乙两人各加工60个陶瓷工艺品,乙开始工作时,甲在研究如何提高工作效率,4小时后才进行加工,这时甲每小时加工的工艺品的个数比乙每小时加工的工艺品的个数多2个,结果甲比乙早1小时完成。求甲、乙两人每小时各加工多少个陶瓷工艺品?
The application of fractional equations has always been the test center for the examination. To answer such questions, it is necessary to carefully examine the questions and analyze them carefully. The key is to find out the basic relational equations in the questions. 1. Example of work efficiency Example 1 Both A and B processed 60 ceramic handicrafts, and when B started work, A worked on how to improve work efficiency and processed it 4 hours later. At that time, the number of handicrafts processed per hour was higher than that of B. The number of handicrafts processed per hour is two, and the result is that A is completed one hour earlier than B. How many ceramic arts and crafts are processed each hour by A and B?
