a)

* Rút gọn : 21/56 = 3/8 ; 60/96 = 5/8

Vì 3 < 5 

=> 3/8 < 5/8 ( hay 21/56 < 60/96 )

Vậy 21/56 < 60/96

\(\text{a)}\)

\(\text{Ta có: }\text{ }\frac{21}{56}=\frac{21:7}{56:7}=\frac{3}{8}\text{ và }\frac{60}{96}=\frac{60:12}{96:12}=\frac{5}{8}\)

       \(\Rightarrow\frac{21}{56}< \frac{60}{96}\left(\frac{3}{8}< \frac{5}{8}\right)\)

\(\text{b)}\)

\(\text{Ta có: }\frac{75}{100}=\frac{75:25}{100:25}=\frac{3}{4}\text{ và }\frac{45}{36}=\frac{45:9}{36:9}=\frac{5}{4}\)    

       \(\Rightarrow\frac{75}{100}< \frac{45}{36}\left(\frac{3}{4}< \frac{5}{4}\right)\)
