近日,在组织学生做练习册时,遇到了这样一道题:1/4<()/()<1/3。我组织学生进行讨论,当学生一筹莫展时,我用了平时最拿手的解决此题的方法进行讲解:先把1/4<()/()<1/3转化成0.25<()<0.33,再在0.25与0.33之间找一个小数,接着再化成分数,要约分的再约分,如0.26=(26)/(100)=(13)/(50),于是得到 Recently, when organizing students to do workbooks, they encountered such a question: 1/4 <() / () <1/3. I organized students to discuss, when the students do nothing, I usually use the best way to solve this problem to explain: first 1/4 <() / () <1/3 into 0.25 <() <0.33, Then find a decimal between 0.25 and 0.33, and then re-into the composition of the sub-sub-sub-divided, such as 0.26 = (26) / (100) = (13) / (50), then get
