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.
\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)
\(1\frac{1}{2};1\frac{1}{3};1\frac{1}{4};1\frac{1}{5};1\frac{1}{6};1\frac{1}{7};1\frac{1}{8}\)\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)
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 \(\frac{3}{2}>\frac{4}{3}>\frac{5}{4}>\frac{6}{5}>\frac{7}{6}>\frac{8}{7}>\frac{9}{8}\)
\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)
\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)
`1/2<4/5<5/6<6/7<7/8<8/9.`
`1/2=1−1/2`
`5/6=1−1/6`
`4/5=1−1/5`
`7/8=1−1/8`
`6/7=1−1/7`
`8/9=1−1/9`
Vì `1/2>1/5>1/6>1/7>1/8>1/9`
`⇒1−1/2<1−1/5<1−1/6<1−1/7<1−1/8<1−1/9`
`⇒1/2<4/5<5/6<6/7<7/8<8/9`

1.1/2 ; 2/3 ; 3/4 ; 4/5 ; 5/6 .
2. 3/2 ; 13/12 ; 7/8 ; 15/22 .
3. 4/7
4. 5/4
mình nghĩ là : 1/2 < 2/3 < 3/4 < 4/5 < 5/6 < 6/7 < 7/8 < 8/9 < 9/10
Thankyou bạn
