a,\(\frac{11}{53}=\frac{22}{106}< \frac{22}{37}\)
b,\(\frac{13}{25}=\frac{52}{100}< \frac{53}{100}\)
a, Ta có : \(MSC=BCNN(53,37)=1961\)
Quy đồng :
\(\frac{11}{53}=\frac{11\cdot37}{53\cdot37}=\frac{407}{1961}\)
\(\frac{22}{37}=\frac{22\cdot53}{37\cdot53}=\frac{1166}{1961}\)
Mà \(\frac{407}{1961}< \frac{1166}{1961}\Rightarrow\frac{11}{53}< \frac{22}{37}\). Vậy : \(\frac{11}{53}< \frac{22}{37}\)
