列分式方程解应用题的基本思路是：审题→设未知数→分析数量关系并找出相等关系→列方程→解方程→检验→写答案，其中对题目进行分析，找出等量关系，是列方程解应用题的．关键．有些简单题目，经过审题和简单的摘录，等量关系立即就可找出来；有些比较复杂的题目，需要采取
The basic idea of the application of column fraction equation solving is: examine the problem → set the unknown number → analyze the quantity relationship and find out the equal relationship → column equation → solution equation → test → write the answer, which analyzes the problem and finds the equal relationship. Column equation solution to the problem. The essential. Some simple topics, after trials and simple excerpts, equal relationships can be found immediately; some more complex topics need to be taken
