Question

So sánh các phân số sau : -11/12 và 17/-18

Answer 1

-11/12 > 17/-18

Answer 2

\(-\dfrac{11}{12}=\dfrac{-11.3}{12.3}=\dfrac{-33}{36}\)

\(\dfrac{17}{-18}=\dfrac{-17}{18}=\dfrac{-17.2}{18.2}=\dfrac{-34}{36}\)

Do \(-33>-34\Rightarrow\dfrac{-33}{36}>\dfrac{-34}{36}\)

Hay \(-\dfrac{11}{12}>\dfrac{17}{-18}\)
