\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)
\(1\frac{1}{2};1\frac{1}{3};1\frac{1}{4};1\frac{1}{5};1\frac{1}{6};1\frac{1}{7};1\frac{1}{8}\)\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)
Vì \(\frac{1}{2}>\frac{1}{3}>\frac{1}{4}>\frac{1}{5}>\frac{1}{6}>\frac{1}{7}>\frac{1}{8}\)
=> \(1\frac{1}{2}>1\frac{1}{3}>1\frac{1}{4}>1\frac{1}{5}>1\frac{1}{6}>1\frac{1}{7}>1\frac{1}{8}\)
Hay \(\frac{3}{2}>\frac{4}{3}>\frac{5}{4}>\frac{6}{5}>\frac{7}{6}>\frac{8}{7}>\frac{9}{8}\)
\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)

`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`
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`
a) 1/2
b) 18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9
Nhớ k cho mk nha
a)1/2
b)Vì 18/17 <17/16 <16/15<15/14< 14/13< 13/12< 10/9
Nên, ta có:
18/17; 17/16; 16/15; 15/14; 14/13; 13/12; 10/9.
a,Sắp xếp: \(\dfrac{8}{45};\dfrac{4}{15};\dfrac{7}{15};\dfrac{3}{5}\)
b,Sắp xếp:\(\dfrac{3}{8};\dfrac{4}{5};\dfrac{47}{40};\dfrac{9}{4}\)
a: \(\dfrac{4}{15}=\dfrac{12}{45}\)
\(\dfrac{3}{5}=\dfrac{27}{45}\)
\(\dfrac{8}{45}=\dfrac{8}{45}\)
\(\dfrac{7}{15}=\dfrac{21}{45}\)
Do đó: \(\dfrac{8}{45}< \dfrac{4}{15}< \dfrac{7}{15}< \dfrac{3}{5}\)
\(\frac{4}{5};\frac{5}{6};\frac{7}{8};\frac{6}{5}\)
