La cau tra loi dung nho kich cho minh nhe!
Ta có : 2/3;4/5;6/5;9/10;3/4;12/11;8/7
2/3=0,66
4/5=0,80
6/5=1,20
9/10=0,90
3/4=0,75
12/11=1,09
8/7=1,14
Vì : 0,66<0,75<0,80<0,90<1,09<1,14<1,20
Nên : 2/3<3/4<4/5<9/10<12/11<8/7<6/5

a: 6/8=1-2/8
7/9=1-2/9
10/12=1-2/12
11/13=1-2/13
17/19=1-2/19
2/8>2/9>2/12>2/13>2/19
=>-2/8<-2/9<-2/12<-2/13<-2/19
=>6/8<7/9<10/12<11/13<17/19
b: 3/5=54/90; 7/9=70/90; 9/10=81/90; 1/3=30/90; 4/20=1/5=18/90

a) \(\frac{5}{9},\frac{1}{2},\frac{1}{3},\frac{4}{3},\frac{7}{6},\frac{13}{9}\)
= \(\frac{10}{18},\frac{9}{18},\frac{6}{18},\frac{24}{18},\frac{21}{18},\frac{26}{18}\)
Từ bé -> lớn:
=> \(\frac{1}{3},\frac{1}{2},\frac{5}{9},\frac{7}{6},\frac{4}{3},\frac{13}{9}\)
