Question

so sánh

22/33 và 60/71

Answer 1

so sánh\(\dfrac{22}{33}\) và \(\dfrac{60}{71}\)

\(\dfrac{22}{33}\)<\(\dfrac{60}{71}\)

Answer 2

\(\dfrac{22}{33}\)= \(\dfrac{22.71}{33.71}\)= \(\dfrac{1562}{2343}\)

\(\dfrac{60}{71}\)= \(\dfrac{60.33}{71.33}\)= \(\dfrac{1980}{2343}\)

Vì \(\dfrac{1562}{2343}\) \(< \)\(\dfrac{1980}{2343}\) nên \(\dfrac{22}{33}\) \(< \) \(\dfrac{60}{71}\)

Answer 3

Ta có : \(\dfrac{22}{33}=\dfrac{2\cdot11}{3\cdot11}=\dfrac{2}{3}=\dfrac{2\cdot30}{3\cdot30}=\dfrac{60}{90}\)

Mà \(\dfrac{60}{90}< \dfrac{60}{71}\Rightarrow\dfrac{22}{33}< \dfrac{60}{71}\)

Vậy \(\dfrac{22}{33}< \dfrac{60}{71}\)
