Question

các bn ơi,giải hộ mình câu này với ạ!!!

so sánh: 33/131 và 53/151 

 

Answer 1

`33/131`

`=4983/(131.151)`

`53/151`

`=6943/(131.151)`

`=>43/151>33/131`

Answer 2

Ta có: \(\dfrac{33}{131}=1-\dfrac{98}{131}\)

\(\dfrac{53}{151}=1-\dfrac{98}{151}\)

mà \(\dfrac{98}{131}>\dfrac{98}{151}\Leftrightarrow1-\dfrac{98}{131}< 1-\dfrac{98}{151}\)

nên \(\dfrac{33}{131}< \dfrac{53}{151}\)

Answer 3

Ta có:

\(1-\dfrac{33}{131}=\dfrac{98}{131}\)

\(1-\dfrac{53}{151}=\dfrac{98}{151}\)

\(\Rightarrow\dfrac{98}{131}>\dfrac{98}{151}\Leftrightarrow\dfrac{33}{131}< \dfrac{53}{151}\) 

Answer 4

33/131 < 53/151
