please

Answer 1

\(MSC:36\)

\(\dfrac{11}{4}=\dfrac{11\times9}{4\times9}=\dfrac{99}{36}\)

\(\dfrac{10}{9}=\dfrac{10\times4}{9\times4}=\dfrac{40}{36}\)

Mà \(\dfrac{99}{36}>\dfrac{40}{36}\Rightarrow\dfrac{11}{4}>\dfrac{10}{9}\)

Answer 2

so sánh qua phân số `11/9`

`11/4>11/9`

`10/9<11/9`

`=>11/4>10/9`

Answer 3

\(\dfrac{11}{4}\) và \(\dfrac{10}{9}\)

Ta có: \(\dfrac{11}{4}=\dfrac{11\times9}{4\times9}=\dfrac{99}{36};\dfrac{10}{9}=\dfrac{10\times4}{9\times4}=\dfrac{40}{36}\)

Vì: \(\dfrac{99}{36}>\dfrac{40}{36}\rightarrow\dfrac{11}{4}>\dfrac{10}{9}\)
