Question

Answer 1

So sánh 2 số với nhau ạ

Answer 2

\(\dfrac{-13}{38}>\dfrac{29}{-88}\)

Answer 3

\(\dfrac{-13}{38}=\dfrac{-13\cdot88}{38\cdot88}=\dfrac{-1144}{38\cdot88}\)

\(\dfrac{-29}{88}=\dfrac{-29\cdot38}{88\cdot38}=\dfrac{-1102}{38\cdot88}\)

mà -1144<-1102

nên \(-\dfrac{13}{38}< -\dfrac{29}{88}\)
