记得有一次评讲试卷时,出现这样一道判断题:如果甲数的3/4和乙数的5/6同样大,那么甲数大于乙数。在评讲时我这样说:我们已经学过分数应用题,占谁的几分之几,谁就是单位“1”的量。在这道题中,甲数的3/4,甲数是单位“1”的量,列式是甲数× 3/4。乙数的5/6,乙数是单位“1”的量, I remember once commenting papers, there is such a judgment: If the number of 3/4 and 5/6 of the same B, then the number of A is greater than the number of B. In my comment, I said: We have already learned the fractional application questions, accounting for who is a few, who is the unit “1” amount. In this question, 3/4 of the number of a, A number is the unit “1” amount, the formula is a number of × 3/4. B 5/6, B is the number of units “1”
