Answer 2

\(\dfrac{6}{25}=\dfrac{6\cdot5}{25\cdot5}=\dfrac{30}{125}\)

Vậy \(\dfrac{14}{125}< \dfrac{30}{125}\Rightarrow\dfrac{14}{125}< \dfrac{6}{25}\)

Ta có: \(\dfrac{6}{25}=\dfrac{30}{125}\)

Vì \(\dfrac{14}{125}< \dfrac{30}{125}=>\dfrac{14}{125}< \dfrac{6}{25}\)

Vậy \(\dfrac{14}{125}< \dfrac{6}{25}\)
