今天,黄老师出了一道让同学们讨论计算方法的题,问题是:有一个服装厂,计划每天生产50件茄克,一个月(以30天计)完成,实际提前5天完成了任务,问每天增产百分之几?比比谁的思路最佳。经过一段时间的思考后,同学们纷纷举手发言。张亚抢先说:“这题简单,数量关系是(实际工效-计划工效)÷计划工效,即[50×30÷(30-5)-50]÷50=20%。”李非说:“还可以这样求:50×[30÷(30-5)]/50-1=20%。”王欧摇摇头说:“你们的方法太麻烦,看我的!30÷(30-5)-1=20%。我
Today, Teacher Huang came up with a question for students to discuss the calculation method. The problem is: there is a garment factory that plans to produce 50 jackets a day, one month (on a 30-day basis) and actually finish the task five days in advance. What percentage of daily output than the best who thought. After a period of thinking, the students raised their hands and spoke one after another. Zhang Ya first said: ”This question is simple, the number of relations is (actual work efficiency - planned ergonomic) ÷ planned ergonomics, that is, [50 × 30 ÷ (30-5) -50] ÷ 50 = 20% 50: 30 / (30-5)] / 50-1 = 20%. “Wang Ou shook his head and said:” Your methods are too troublesome and look at me! 30 ÷ ( 30-5) -1 = 20%.
