\(\frac{22}{27}+\frac{37}{67}=\left(1-\frac{5}{27}\right)+\left(1-\frac{30}{67}\right)\)

\(\frac{31}{36}+\frac{377}{677}=\left(1-\frac{5}{36}\right)+\left(1-\frac{300}{677}\right)\)

+ \(\frac{5}{27}>\frac{5}{36}\Rightarrow1-\frac{5}{27}< 1-\frac{5}{36}\left(1\right)\)

+ \(\frac{30}{67}=\frac{300}{670}>\frac{300}{677}\Rightarrow1-\frac{30}{67}< 1-\frac{300}{677}\) (2)

Từ (1) và (2) \(\Rightarrow\frac{22}{27}+\frac{37}{67}< \frac{31}{36}+\frac{377}{677}\)

Vsu

Ta có phân số trung gian -22/45 và -54/103 là -22/103

Suy ra -22/103<-22/45;-22/103>-51/103

Suy ra -22/45>-51/103

Dẽ mà bạn

de ma can gi phai hoi

quy đồng mà giải

Có : vì -22/103> -51/103

Suy ra : -22/44 > -51/103

-22/44 > -51/103

-22/44<-51/103

\(\frac{46}{45}=1+\frac{1}{45},\frac{2012}{2011}=1+\frac{1}{2011}\)

Có \(2011>45>0\Rightarrow\frac{1}{45}>\frac{1}{2011}\)

Do đó \(\frac{46}{45}>\frac{2012}{2011}\).

\(\frac{2011}{2010}>1>\frac{16}{17}\).

\(\frac{22}{45}< \frac{22}{44}=\frac{1}{2}=\frac{51}{102}< \frac{51}{101}.\)

22/45 < 51/101

\(\frac{-22}{45}>-\frac{51}{103}\)
