小学数学教材中对最简分数的定义为“分子、分母是互质的分数,叫做最简分数。”笔者认为这个定义值得商推。顾名思义,所谓“最简分数”,第一,应从“最简”两字上去考虑。在小学教材中规定:“计算结果……是假分数的,要化成带分数。”这是因为用来表示数值的大小,带分数要比假分数简明。例如3/2小时,还 Primary mathematics textbooks for the most simple fraction of the definition of “numerator, denominator is a cross-quality score, called the most simple fraction.” I think this definition is worth the push. As the name suggests, the so-called “most concise”, first, should be from the “minimal” word to consider. In the primary school textbook provides: “The calculation results ... ... is a fake score, to be turned into a score.” This is because the value used to indicate the size of the band fraction than the fraction of concise. For example 3/2 hours, still
