工程应用题,在课本中是利用分数应用题的解法来解答的。其实工程应用题还有比较特殊的解法,有时比用分数应用题的解法更容易被孩子理解和掌握。一、倍数解法倍数解法,就是从工程问题中的工作时间之间或是工作效率之间存在的倍数关系入手,展开解题思路。例1 要修一条公路,甲队独修需要8天完成,乙队独修需要16天完成。两队合修若干天后,乙队
Engineering application questions, in the textbook is to use the answer to the solution to the problem. In fact, engineering problems there is a more special solution, sometimes more difficult to be understood and mastered by the child than the solution of the fractional application. First, the multiple solution Multiplier solution, that is, from the engineering problems in the working hours or between the working efficiency of the existing multiple relationship to start solving the problem. Example 1 To repair a road, team A need 8 days to complete the autonomy, Team B need 16 days to complete the autonomy. Two teams co-repair a few days later, team B.
