分数应用题和整数应用题是不同类型的应用题,分数是在整数的基础上产生的。那么,分数应用题与整数应用题是否存在着联系呢?下面把整数倍数三类应用题和分数(百分数)三类应用题列成表格。通过对右表进行对照比较发现:整数倍数应用题突出的是“倍数”,分数(百分数)应用题突出的是“分数”。如果把整数倍数三类应用题中的“倍数”分别换成“分数”,便分别变成分数(百分数)的三类应用题,其它的条件和问题则完全相同。由此可见,分数(百分数)应用题与整数倍数应用题存在着内在的、本质的联系,可以认为.分数(百分数)三类应用题是分别由整数倍数三类应用题扩展延伸而来的。
Fractional application questions and integer application questions are different types of application questions, scores are generated on the basis of integers. Then, the fractional application questions and integer application questions whether there is a relationship? Here are the integer multiples of the three types of application questions and scores (percentage) three application questions into a table. By comparing the right table comparison found: Integer multiple application questions highlight the “multiple”, the score (percentage) application questions highlight the “score.” If the “multiples” of the three types of application multiples are replaced by “scores,” they become the three types of application questions respectively with scores (percentages), and the other conditions and problems are exactly the same. Thus, there is an inherent and essential relationship between the fraction (%) application questions and the integer multiple application questions, and it can be considered that the fraction (%) three kinds of application questions are extended by three types of application questions respectively by integer multiples .
