Thằng tĩn ah

Khôn ghê hen

scsc/?/.

Háy tính giúp tôi

\(\dfrac{9}{5}< \dfrac{17}{13}< \dfrac{113}{110}< \dfrac{2013}{2010}\)

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.

=> \(\frac{1}{3}< \frac{4}{5}< \frac{41}{45}< \frac{11}{9}< \frac{11}{5}\) 

\(\frac{1}{3};\frac{4}{5};\frac{41}{45};\frac{11}{9};\frac{11}{5}\)

         HOK TỐT

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

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

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
