Question

[Cường Đubai]

2 phần 3 ...... 3 phần 4 so sánh

Answer 1

[Dora]

\(\dfrac{2}{3}=\dfrac{2 \times 4}{3 \times 4}=\dfrac{8}{12}\)

\(\dfrac{3}{4}=\dfrac{3 \times 3}{4 \times 3}=\dfrac{9}{12}\)

 Vì `8 < 9=>`\(\dfrac{8}{12} < \dfrac{9}{12}\)

  Hay \(\dfrac{2}{3} < \dfrac{3}{4}\)

Answer 2

[Nguyễn Thị Thương Hoài]

\(\dfrac{2}{3}\) = 1-\(\dfrac{1}{3}\) < 1 - \(\dfrac{1}{4}\) = \(\dfrac{3}{4}\)

vậy 2/3<3/4
