自习课上,同学们在讨论一道思考题,题目是这样的:某工厂要做一批零件,原计划每天生产40个,实际每天比原计划多生产10个,结果提前5天完成任务,原计划生产多少个零件?有同学是这样做的:首先假设按原计划的天数生产,那5天依然在生产,可生产40×5=200(个)零件。这200个是实际每天多生产10个零件而多出来的,由此可以求出实际生产的天数是200÷10=20(天)。原计划生产的零件就是实际生产的零件,
Self-study class, the students are discussing a question of thinking, the title is this: a factory to do a number of parts, the original plan to produce 40 daily, the actual daily production of 10 more than the original plan, the results completed 5 days ahead of schedule, the original How many parts are planned to be produced? Some students did the following: First, suppose that they were produced as planned for the first five days and are still in production for 5 days, producing 40 × 5 = 200 parts. These 200 are the actual production of more than 10 parts per day more, which can be obtained from the actual production of the number of days is 200 ÷ 10 = 20 (days). The original planned production of parts is the actual production of parts,
