a) \(\frac{22}{33}\)và \(\frac{60}{71}\)
Ta có :
\(1-\frac{22}{33}=\frac{11}{33}\)
\(1-\frac{60}{71}=\frac{11}{71}\)
Vì \(\frac{11}{33}>\frac{11}{71}\)nên \(\frac{22}{33}< \frac{60}{71}\)
b)\(\frac{141}{893}\)và \(\frac{149}{901}\)
Ta có :
\(1-\frac{141}{893}=\frac{752}{893}\)
\(1-\frac{149}{901}=\frac{752}{901}\)
Vì \(\frac{753}{893}>\frac{753}{901}\)nên \(\frac{141}{893}< \frac{149}{901}\)
a, 22/33 va 60/71
22/33=2/3=2x71/3x71=142/213
=> 142/213<180/213 Vay 22/33<60/71
60/71=60x3/71x3=180/213
b, 141/893 va 149/901
ta có :
1-141/893=752/893
1-149/901=752/901
Vi 752/893>752/901 => 141/893>149/901
