So sánh -173/457 và -16/47

So sánh -173/457và -16/47

Answer 1

So sánh:

\(-\dfrac{173}{457}\)  và  \(-\dfrac{16}{47}\)

\(\dfrac{-173}{457}=\dfrac{-173\times47}{457\times47}=\dfrac{-8131}{21479}\)

\(\dfrac{-16}{47}=\dfrac{-16\times457}{47\times457}=\dfrac{-7312}{21479}\)

Vì: \(-8131< -7312\)

=> \(\dfrac{-173}{457}< \dfrac{-16}{47}\)
