Question

so sánh 3 phần 5 và 33 phần 55

 

Answer 1

ta có : `3/5=(3xx11)/(5xx11)=33/55`

`33=33->3/5=33/55`

Answer 2

`3/5=3/5`

`33/55=(33:11)/(55:11)=3/5`

Vì `3=3` nên `3/5=3/5`

Vậy `3/5=33/55`

Answer 3

\(\dfrac{33}{55}=\dfrac{33:11}{55:11}=\dfrac{3}{5}=>\dfrac{3}{5}=\dfrac{33}{55}\)

Answer 4

\(\dfrac{3}{5}=\dfrac{3}{5}\)

\(\dfrac{33}{55}=\dfrac{33:11}{55:11}=\dfrac{3}{5}\)

\(\Rightarrow\dfrac{3}{5}=\dfrac{33}{55}\)

Answer 5

\(\dfrac{33}{55}=\dfrac{3\times11}{5\times11}=\dfrac{3}{5}\)

\(\Rightarrow\dfrac{3}{5}=\dfrac{33}{55}\)
