Question

[Nguyễn Ngọc Khuê]

3/7 lớn hơn hay nhỏ hơn 1/2 ?

Answer 1

[Hquynh]

\(MSC:14\)

\(\dfrac{3}{7}=\dfrac{3\times2}{7\times2}=\dfrac{6}{14}\)

\(\dfrac{1}{2}=\dfrac{1\times7}{2\times7}=\dfrac{7}{14}\)

Vì \(6< 7\Rightarrow\dfrac{6}{14}< \dfrac{7}{14}\)

\(\Rightarrow\dfrac{3}{7}< \dfrac{1}{2}\)
