Question

So sánh 58/57 và 65/63

Answer 1

Ta có:

`58/57=[58.63]/[57.63]=3654/3591`

`65/63=[65.57]/[63.57]=3705/3591`

Vì `3654 < 3705=>3654/3591 < 3705/3591`

  Hay `58/57 < 65/63`

Answer 2

\(\dfrac{58}{57}=\dfrac{58.63}{57.63}=\dfrac{3654}{3591}\\ \dfrac{65}{63}=\dfrac{65.57}{63.57}=\dfrac{3705}{3591}\\ 3654< 3705\\ =>\dfrac{58}{57}< \dfrac{65}{63}\)
