`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`

1/2; 4/5;5/6;6/7;7/8;8/9

1/2 ; 4/5 ; 5/6 ; 6/7 ; 7/8; 8/9

1/2 < 4/5 < 5/6 < 6/7 < 7/8 < 8/9

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

Đáp án là 1/2,2/3,3/4,4/5,5/6,

\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)

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

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    \(\frac{3}{2}>\frac{4}{3}>\frac{5}{4}>\frac{6}{5}>\frac{7}{6}>\frac{8}{7}>\frac{9}{8}\)

\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)

\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)\(\frac{3}{2};\frac{4}{3};\frac{5}{4};\frac{6}{5};\frac{7}{6};\frac{8}{7};\frac{9}{8}\)

9/8,8/7,7/6,6/5,5/4,4/2,3/2

mình nghĩ là : 1/2 < 2/3 < 3/4 < 4/5 < 5/6 < 6/7 < 7/8 < 8/9 < 9/10

Thankyou bạn

giúp minhhf với

\(\dfrac{1}{5};\dfrac{4}{11};\dfrac{7}{12};\dfrac{3}{4};\dfrac{5}{6};\dfrac{3}{2};\dfrac{8}{3}\)

Các phân số theo thứ tự từ bé đến lớn là : \(\frac{5}{9};\frac{3}{7};\frac{2}{3}\)

Các phân số theo thứ tự từ lớn đén bé là : \(\frac{4}{3};\frac{5}{6};\frac{5}{18}\)

Học tốt!!!
