1 câu trả lời

`(1919.161616)/(323232.3838)`

`= (19.101.16.10101)/(16.10101.2.19.101.2)`

`= 1/(2.2)`

`= 1/4`

Ta có :

`1/4 = (1.51)/(4.51) = 51/204`

`25/102 = (25.2)/(102.2) = 50/204`

Vì `51 > 50` nên `1/4 > 25/102` hay `(1919.161616)/(323232.3838) > 25/102`

Vậy `(1919.161616)/(323232.3838) > 25/102`
