Question

Chuyển các phân số thành hỗn số:

8/3; 15/6; 85/12; 5/2.

Answer 1

\(\dfrac{8}{3}=2\dfrac{2}{3}\)

\(\dfrac{15}{6}=\dfrac{5}{2}=2\dfrac{1}{2}\)

\(\dfrac{85}{12}=7\dfrac{1}{12}\)

\(\dfrac{5}{2}=2\dfrac{1}{2}\)

Answer 2

`8/3=2 2/3`

`15/6= 2 3/6`

`85/12= 7 1/12`

`5/2=2 1/2`

Answer 3

\(\dfrac{8}{3}=2\dfrac{2}{3}\)  ;  \(\dfrac{15}{6}=2\dfrac{3}{6}\) ; \(\dfrac{85}{12}=7\dfrac{1}{12}\) ;  \(\dfrac{5}{2}=2\dfrac{1}{2}\)

Answer 4

\(\dfrac{8}{3}=2\dfrac{2}{3}\)

\(\dfrac{15}{6}=2\dfrac{1}{2}\)

\(\dfrac{85}{12}=7\dfrac{1}{12}\)

\(\dfrac{5}{2}=2\dfrac{1}{2}\)

Answer 5

`8/3=2 2/3`

`15/6=2 1/2`

`85/12=7 1/12`

`5/2=2 1/2`

Answer 6

`8:3=2(dư2)`

ta có :

`8/3=2 2/3`

`15/6=5/2`

`5:2=2(dư1)`

ta có :

`5/2=2 1/2`

áp dụng tương tự :

`85/12=7 1/12`

`5/2=2 1/2`
