Question

Hãy sắp xếp các phân số sau theo thứ tự từ bé đến lớn.

\(\dfrac{1}{3}\);\(\dfrac{3}{2}\);\(\dfrac{5}{6}\);\(\dfrac{3}{4}\)

Answer 1

`MSC:12`

`1/3 = (1xx4)/(3xx4)= 4/12`

`3/2=(3xx6)/(2xx6)=18/12`

`5/6=(5xx2)/(6xx2)=10/12`

`3/4=(3xx3)/(4xx3)=9/12`

`-> 4/12; 9/12; 10/12;18/12`

`->1/3; 3/4;5/6;3/2`

Answer 2

có `1/3=4/12`

`3/2=18/12`

`5/6=10/12`

`3/4=9/12`

vì `4<9<10<18`

`=>4/12<9/12<10/12<18/12`

`=>1/3<3/4<5/6<3/2`

`=>` sắp xếp: `1/3;3/4;5/6;3/2`
