Compare the fractions
21/28
and
6/9

Given Fractions:  
21/28
and
6/9

Since the denominators are not common (not the same), we need to find the Least Common Denominator (LCD), which is equivalent to the Least Common Multiple of 9 and 28:
LCD = LCM(9, 28) = 252
Express the given fractions as equivalent fractions with respect to the LCD (252):
21/28
=
189/252
  and  
6/9
=
168/252
Since the equivalent fractions have common denominators, we can compare the numerators:
189 is greater than 168  (189 > 168)
As a result,  
189/252
  is greater than
168/252
Therefore,  
21/28
  is greater than
6/9
,  
21/28
>
6/9
