对比较分数大小的方法,现归类举例如下: 一、同分母分数比大小同分母分数,分子大的分数较大,分子小的分数小。如:5/7>3/7。二、同分子分数比大小分子相同的两个分数,分母小的分数较大,如:1/2>1/5。三、两个真分数分子和分 The method of comparing the fractional size is now classified as follows: First, the same denominator fractional size than the same denominator fraction, a larger fraction of large molecules, a small fraction of small molecules. Such as: 5/7> 3/7. Second, the same fraction of molecules than the size of the same two molecules, denominator small fraction, such as: 1/2> 1/5. Third, two real scores of molecules and points
