“约等号”与“等号”是一对非常要好的兄弟,他们两个同在数学百货公司工作。“等号”是百货公司的总经理,“约等号”则是百货公司的财务经理。一天,“等号”把“约等号”叫进了办公室,十分严肃地对“约等号”说:“你和我虽然是兄弟,但公事公办,我这人向来大公无私,从来不会包庇任何人,我问你,为什么要做假账?”“约等号”一脸疑惑:“怎么会呢?我一贯按规办事,怎么会做假账呢?”“等号”十分生气:“还不承认!那我问你,我们旗下的酒店购入了530千克油,每个桶最多装25千克油。530÷25=21.2(个),油桶只能用整数个,那按四舍五入的原则取近似值,不应该是21个吗?应该用21个油桶,你为何写用22个?”
“Equal sign ” and “Equal sign ” is a pair of very good brothers, both of them work in a math department store. “Equals ” is the general manager of the department store, “equal sign ” is the department store’s financial manager. One day, the “” equals “put ” about equal sign “into the office, very serious on the” equal sign “said: ” Although you and I are brothers, but the public, my people Always have selflessness, never conceal any person, I ask you why you want to do a fake account? “” About equal sign “A look of doubt: ” how? I have always behaved according to rules, “” “Is very angry: ” does not recognize! Then I ask you, our hotel bought 530 kg of oil, each barrel up to 25 kg of oil .530 ÷ 25 = 21.2 ( ), Drums can only use an integer, then according to the principle of rounding approximations, should not be 21? Should use 21 drums, why do you write with 22?
