(一) 前言我們在進行分數的加減运算時,对於帶分數,有兩种不同的运算方法:一种是先將带分数化为假分数之後,再按分數加減法的一般法則去進行运算;另一种是不把带分數化为假分數,而是採用带分數的整數部分与整數部分進行相加減的运算,分數部分与分數部分進行相加減的运算,然後再將这兩部分的結果合併在一起。初中一年級的学生在未進入初中之前,对帶分數加減法的兩种运算法則,大致都已学过一些,可是当他們在初中学習到分數乘法關於带分數相乘的問题時,我們教給学生必須先將帶分數化为假分數後,再按分數乘法的一般法則去运算,但是对於带分数不化为假分数能否進行乘的运算的問題,便閉口不談,而一些鑽研性較强的
(I) Introduction When we perform addition and subtraction of scores, there are two different methods for calculating the number of points. One is to first convert the band score into a false one, and then perform the operation according to the general rule of the addition and subtraction of the score. The other is not to turn a band into a false score. Instead, use an integer part with a fraction and an integer part to add and subtract. The fraction and fraction are added and subtracted, and then the results of the two parts are added. combined together. In the first grade of junior high school students, before they entered junior high school, they generally learned some of the two algorithms for adding and subtracting the scores, but when they learned the problem of multiplication of scores in the junior high school, we taught Students must first classify the scores into false scores and then follow the general rule of score multiplication. However, if the score score does not turn into a false score, the multiplication operation can be ignored. Strong
