Question

\(\dfrac{2}{5}...\dfrac{5}{2}\) 

Answer 1

ta có : `2/5 = (2xx2)/(5xx2)=4/10 ; 5/2=(5xx5)/(2xx5)= 25/10`

`=> 2/5 < 5/2`

Answer 2

\(\dfrac{2}{5}=\dfrac{2\times2}{5\times2}=\dfrac{4}{10}\)

\(\dfrac{5}{2}=\dfrac{5\times5}{2\times5}=\dfrac{25}{10}\)

\(=>\dfrac{2}{5}< \dfrac{5}{2}\)

Answer 3

= \(\dfrac{4}{10}\)...\(\dfrac{25}{10}\)

= <
