分数(百分数)应用题,是根据题目的标准量、比较量和分率的相互关系,由已知两个量求第三个量的。但只要弄清分率这个概念,掌握解题规律也就不难了。分率是两个同类量相比较的结果,即比较量是标准量的几分之几或百分之几。比较量与其对应的分率,是和标准量互相对应、依存的两个方面。应该指出,同类量才能比 Score (percentage) application questions, is based on the subject of the standard amount, comparison and fractional relationship between the two known quantities for a third quantity. But as long as you understand the concept of fractional rate, it is not difficult to grasp the law of solving problems. The fractional rate is the result of comparing two similar quantities, that is, whether the comparison is a fraction or a few percent of the standard amount. Compared with the corresponding volume fraction, and the standard amount of mutual correspondence, dependent on two aspects. It should be pointed out that the same amount of talent than
