\(x=\frac{-17}{23}\)
\(y=\frac{-171717}{232323}=\frac{\left(-171717\right):10101}{232323:10101}=\frac{-17}{23}\)
\(\Rightarrow x=y\)

-171717/232323 = -10101x17/10101x23 = -17/23
mà -17/23 = -17/23
do đó -17/23 = -171717/232323

a, -1/4<0
1/100>0
=> -1/4<1/100
b) -11/32=-11.25/ 32.25=-275/800
-25/ 76=-25.11/ 76.11=-275/ 836

mà 31/19< 31/17
=> 1-31/19> 1-31/17
=>-12/19> -14/17
