Question

35分之17,53分之26和223分之111比较大小

最好用通分的方法

Answer 1

1)
2 × 17/35 ＝ 34/35
2 × 26/53 = 52/53
2 × 111/223= 222/223
由于： 222/223 > 52/53 > 34/35
因此： 111/223 > 26/53 > 17/35
2) M = 35×53×223 ＝ 413665
17/35 = 17×53×223/A = 200923/A
26/53 = 26×35×223/A = 202930/A
111/223 = 35×53×111/A = 205905/A
通分之后看出：111/223 > 26/53 > 17/35
