a, \(\dfrac{313}{370}=1-\dfrac{57}{370}\\ \dfrac{314}{371}=1-\dfrac{57}{371}\)
Mà: \(\dfrac{57}{370}>\dfrac{57}{371}\Rightarrow1-\dfrac{57}{370}< 1-\dfrac{57}{371}\)
\(\Leftrightarrow\dfrac{313}{370}< \dfrac{314}{371}\)
b, \(-\dfrac{3}{4}=-0,75\)
Do: \(0,75< 0,8\)
\(\Rightarrow-0,75>-0,8\)
\(\Leftrightarrow\dfrac{-3}{4}>-0,8\)
c, \(-\dfrac{151515}{323232}< 0< \dfrac{3}{7}\)
hay \(\dfrac{-151515}{323232}< \dfrac{3}{7}\)
