Compare the fractions
2/5
and
1/2

Given Fractions:  
2/5
and
1/2

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 2 and 5:
LCD = LCM(2, 5) = 10
Express the given fractions as equivalent fractions with respect to the LCD (10):
2/5
=
4/10
  and  
1/2
=
5/10
Since the equivalent fractions have common denominators, we can compare the numerators:
4 is less than 5  (4 < 5)
As a result,  
4/10
  is less than
5/10
Therefore,  
2/5
  is less than
1/2
,  
2/5
<
1/2
