应用题涉及的内容很多,数量关系又千变万化,怎样才能提高复习效率呢?现在向你介绍四种方法:一、用条件联想——贵在想得多一道应用题,它总有若干个已知条件,用其中相关的已知条件分别做不同的组合,可以推出一些新的条件(即中间问题),再筛选出有用的,一步步向最终问题逼近,就可以顺利找到解题路径。如:小冬读一本书,第一天读了它的2/5,第二天又读了余下的1/2,这时没读的还有80页,这本书共有多少页?
Application topics covered a lot, the relationship between the ever-changing, how can we improve the review efficiency? Now to introduce you to four ways: First, the use of conditional association - you think much of an application problem, it always has a number of known Conditions, with the relevant known conditions were made of different combinations, you can introduce some new conditions (that is, intermediate problems), and then screened useful, step by step to the final problem approximation, you can successfully find the path to solve the problem. Such as: a small winter reading a book, the first day of reading it 2/5, the next day and read the remaining 1/2, then did not read there are 80 pages, the book total number of pages?
