\(\dfrac{22}{33}=\dfrac{22:11}{33:11}=\dfrac{2}{3}\)
Ta có: 
Mẫu số chung 2 phân số: 57
\(\dfrac{12}{19}=\dfrac{12*3}{19*3}=\dfrac{36}{57}\)
\(\dfrac{2}{3}=\dfrac{2*19}{3*19}=\dfrac{38}{57}\)
Vì \(36< 38\) nên\(\dfrac{36}{57}< \dfrac{38}{57}\)
Vậy \(\dfrac{12}{19}< \dfrac{22}{33}\)

\(\dfrac{22}{33}\)=\(\dfrac{22:11}{33:11}\)=\(\dfrac{2}{3}\)=\(\dfrac{2\times6}{3\times6}\)=\(\dfrac{12}{18}\)>\(\dfrac{12}{19}\)

Ta có: 22/33 = 2/3 = 12/18

12/19 < 12/18 

Vậy 12/19 < 22/33

\(\frac{1212}{1313}=\frac{101.12}{101.13}=\frac{12}{13}\)

12/13 = 12/13 

Vậy 12/13 = 1212/1313

124124/125125 = \(\frac{1001.124}{1001.125}=\frac{124}{125}\)

1 - 123/124 = 1/124 ; 1 - 124/125 = 1/125

Nên 123/124 < 124/125

Vậy 123/124 < 124124/125125

a) Ta có : 22/33 = 2/3 = 12/18

Vì 12/18 > 12/19 nên 12/19 < 22/33

b) Ta có : 1212/1313 = 12/13

Vì 12/13 = 12/13 nên 12/13 = 1212/1313

c) Ta có : 124124/125125 = 124/125

1 - 123/124 = 1/124

1 - 124/125 = 1/125

Vì 1/124 > 1/125 nên 123/124 < 124124/125125

Ta có:\(\frac{22}{33}\)=\(\frac{2}{3}\)=\(\frac{12}{18}\)

Do18<19=>\(\frac{12}{19}\)<\(\frac{12}{18}\)

Vậy\(\frac{12}{19}\)<\(\frac{22}{33}\)

bạn tự quy đồng nên rồi so sánh nha

Ta có :22/33=2/3

So sánh : 12/19 và 2/3

Ta có :12/19 giữ nguyên ; 2/3=12/18

vì 12/19<12/18 nên 12/19<22/33

24/10<25/10

Vì 4/5<1,5/3>1=>4/5<5/3

Vì 15/22<19/22,19/21>19/22=>15/22<19/21

a, \(\dfrac{23}{27}\) > \(\dfrac{22}{27}\) > \(\dfrac{22}{29}\)

Vậy \(\dfrac{23}{27}\) > \(\dfrac{22}{29}\)

b, \(\dfrac{25}{74}\) > \(\dfrac{24}{74}\) = \(\dfrac{12}{37}\)

Vậy \(\dfrac{25}{74}\) > \(\dfrac{12}{37}\)

\(\frac{12}{13}>\frac{22}{33}\)

\(\frac{123}{123}=\frac{124124}{125125}\)

Chuyển từ phân số thành hỗn số :

\(\frac{14}{5}=2\frac{4}{5},\frac{29}{7}=4\frac{1}{7},\frac{100}{24}=4\frac{1}{6},\frac{32}{7}=4\frac{4}{7},\frac{315}{100}=3\frac{3}{20}\)

\(\frac{31}{15}=2\frac{1}{15},\frac{89}{10}=8\frac{9}{10},\frac{25}{6}=4\frac{1}{6},\frac{124}{50}=2\frac{12}{25},\frac{35}{4}=8\frac{3}{4}\)

a ) Ta có 

\(\frac{29}{33}>\frac{29}{37}\)( đồng tử khác mẫu )

\(\frac{22}{37}< \frac{29}{37}\)( đồng mẫu khác tử )

=> \(\frac{29}{33}>\frac{29}{37}>\frac{22}{37}\)

b )  \(\frac{163}{257}< \frac{163}{221}\)

  \(\frac{162}{257}>\frac{149}{257}\)

  \(\Rightarrow\frac{163}{221}>\frac{163}{257}>\frac{149}{257}\)

a) ta có: \(\frac{22}{37}< \frac{29}{37}\)

\(\frac{29}{33}>\frac{29}{37}\)

\(\Rightarrow\frac{22}{37}< \frac{29}{37}< \frac{29}{33}\)

b) ta có: \(\frac{163}{257}>\frac{149}{257}\)

\(\frac{163}{221}>\frac{163}{257}\)

\(\Rightarrow\frac{163}{221}>\frac{163}{257}>\frac{149}{257}\)
