The technology is as follows:
1. Hypothesis: Set an unknown number according to the meaning of the question. Generally speaking, the set unknown is the distribution of workers.
2. Column: Column represents the total output of two types of products.
3. Search: Find the least common multiple of specific data appearing in the matching relationship.
Fourth class. : According to the relationship between the least common multiple and the product matching, distribute and multiply, and write the equation.
There are two common types.
1, production facilities: the total number of people is known, and they are divided into several parts to engage in the production of different projects, and the proportion of engineering quantity of each project meets the overall requirements.
2. Distribution: transfer some people (things) from Party A to Party B to satisfy a certain quantitative relationship, or transfer some people (things) from a third party to Party A and Party B to satisfy a certain quantitative relationship. The basic equivalence relation is that the number of people (things) in A+the number of people (things) in B equals the total number of people (things).
The idea of solving complex application problems is composed of two or more interrelated simple application problems.
1, understanding the meaning of the question is to find out the known conditions and requirements in the application question.
2. Analyzing the quantitative relationship means analyzing the relationship between known quantity and unknown quantity, known quantity and unknown quantity, finding a solution to the problem, and determining what is first, then what is best.
3, column solution, that is, according to the analysis, list the formula and calculate.
4. Check the calculation, give the answer, that is, check whether the solution process is reasonable, whether the result is correct, whether it is consistent with the original question, and finally write the answer.
Extended data:
There are many types of practical application problems of linear equations with one variable. This paper mainly introduces the matching problems in practical application. When solving practical application problems, we must first understand the meaning of the problem and find out the known and unknown quantities in the problem. When solving the unknown, we can choose the direct method and the indirect method.
The key to solving the problem is to find out the quantitative relationship in the problem, and it is not easy to make mistakes in order to support the proportional problem solving. The basic property of proportion, the inner product equals the outer product, that is, A: B = C: D, then bc=ad.
