五一长假,小惠去乡下看望外公、外婆.乡村里那清新的空气、秀美的山水,以及外公外婆的关怀疼爱,使小惠特别开心.有一天,外公要带着100元钱去镇上赶集.他请小惠帮他把100元(有足够的零钱)分成多份,分别包在几个小包里,使他买东西时,从1角到100元,不管要花多少钱(只计元角,不计分),只要从中挑出几包付钱,不用找钱.小惠可从来没有做过这样的数学题,但觉得挺有意思.小惠想,应该有一包是1角钱的,不然买1角钱的东西怎么办呢?为了买2角钱的东西,有两种包法:一种是再包一个1角钱的包,另一种是包一个2角钱的包。哪种方法更好呢?当然是第二种方法好,因为第二种方法不但可以买2角钱的东西,还可以跟第一包合起来买3角钱的东西.
On the May Day holiday, Xiaohui went to the countryside to visit her grandfather and grandmother. The fresh air in the country, the beautiful scenery and the care and affection of grandparents made Xiaohui very happy. One day, my grandfather had to bring 100 yuan to go to the town to catch up. He asked Xiaohui to help him to divide 100 yuan (with enough change) into several small bags, so that when he bought anything from 1 to 100 yuan, no matter how much money he needed (only Yuan Yuan, Do not score), as long as you pick out a few packets to pay, do not have to find money. Xiaohui may never have done such a math problem, but I feel very interesting. Xiaohui think, there should be a bag of 1 cent, or buy a dime How to do things? In order to buy 2 dimes, there are two kinds of package methods: one is to pack a dime package, and the other is to package a dime package. Which method is better? Of course, the second method is good, because the second method can not only buy 2 cents, but also with the first package to buy 3 cents.
