有的同学一看到应用题就害怕，不知从哪儿下手分析，下面谈谈分析应用题的一些基本方法。

Some students are frightened at the sight of the application questions, do not know where to start analysis, the following talk about the analysis of some basic methods of application problems.

首先要学好简单应用题，这是解答应用题的基本功。因为复合应用题都是由几个简单应用题组成的。

First of all, we should learn simple application questions, which is the basic skill of solving practical problems. Because compound questions are made up of several simple application questions.

怎样分析复合应用题呢？由于思维过程不同，分为综合法和分析法两种。综合法是从已知条件出发，逐步推出要解决的问题；分析法是从问题出发，逐步追溯到已知条件。例如：红叶服装厂计划做66O套衣服，已经做了5天，平均每天做75套。剩下的要3天做完，平均每天做多少套？

How to analyze the compound application problem? Because of the different thinking process, it can be divided into two types: comprehensive method and analytical method. The comprehensive method is to start from the known conditions and gradually introduce the problems to be solved; the analytical method is to start from the problems and gradually trace back to the known conditions. For example, Hongye garment factory plans to make 66O suits, has been doing 5 days, an average of 75 sets per day. The remaining 3 days to complete, the average number of sets per day?

用分析法分析：要求平均每天做多少套，就必须知道剩下多少套（未知）和剩下的要几天做完（已知）；要求剩下多少套就必须知道计划做多少套（已知）和已经做了多少套（未知）；要求已经做了多少套就必须知道平均每天做多少套（已知）和做了几天（已知）。这样一步一步找出新的问题中的数量关系，直到新的问题所要求的数量关系都成为已知条件为止。

Analysis by analysis: it is necessary to know how many sets a day to do on the average, it is necessary to know how many sets (unknown) and the rest of the rest to finish (known); how many sets that are left must know how many sets (known) and how many sets have been done (unknown); and how many sets have been done must know the average daily How many sets (known) and have been done for several days (known). This step by step finds the quantitative relationship in the new problem until the quantitative relationship required by the new problem becomes a known condition.

用综合法分析：题中告诉我们，已经做了5天，平均每天做75套，我们能求出5天做的套数；已知计划做660套和5天做的套数，我们能求出剩下的套数；已知剩下的套数和剩下做的天数，我们能求出剩下平均每天做的套数。根据题中给的已知条件，一步步找到需要解答的问题。

In a comprehensive analysis, the problem tells us that we have done 5 days with an average of 75 sets a day and we can figure out the set of 5 days; we have planned to do 660 sets and 5 days, and we can figure out the rest of the set; we know the rest of the set and the remaining days, we can find the rest of the average daily number. According to the known conditions given in the title, step by step, we need to find answers to the questions.

分析应用题时两种方法经常是互相配合，灵活运用。用综合法分析要随时照顾要求的问题，注意已知条件和问题的关系；用分析法分析要随时照顾已知条件，注意问题和已知条件的关系。不论用什么方法分析应用题，都要认真审题，理解题意，通过分析已知条件和问题间的数量关系，找出中间问题（也叫关键问题），最后求得应用题的正确解答。

The two ways of analyzing application questions are to cooperate with each other and apply them flexibly. Use the comprehensive method to take care of the requirements at any time, pay attention to the relationship between the known conditions and the problems, and use the analytical method to take care of the known conditions at any time and pay attention to the relationship between the problems and the known conditions. No matter what method is used to analyze the application questions, we should carefully examine the questions, understand the meaning, and find out the intermediate problems (also called the key problems) by analyzing the known conditions and the quantitative relationship between the problems, and finally get the correct answers to the application questions.
