(一)小学通用五年制数学课本第75面,有这样一句话:“整数可以化成分母是任意自然数的假分数.”我们认为,这句话是错误的,至少“0”这个整数就不能化成假分数.因为?、?、?……都不是分子大于或等于分母的分数.此外,用负整数化假分数时,所得结果为负数,而假分数都是等于或大于1的数,因此也很难说这一结论完全适用于负整数.为使这一结论成立,我们建议将这句话中的“整数”改 (A) The first five-year universal primary school mathematics textbook 75th, there is such a sentence: “integer can be converted into a denominator is an arbitrary natural number of false points. ” We think that this sentence is wrong, at least “This integer can not be turned into an unfractionized fraction because neither?,?,? ... is not a fraction of the numerator greater than or equal to the denominator.” Furthermore, when negative integers are used, the result is negative and the false fraction is equal to or greater than 1, so it is hard to say that this conclusion is entirely applicable to negative integers. To make this conclusion hold, we propose to change “” in this sentence
