Compare the fractions
3/8
and
2/5

Given Fractions:  
3/8
and
2/5

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 5 and 8:
LCD = LCM(5, 8) = 40
Express the given fractions as equivalent fractions with respect to the LCD (40):
3/8
=
15/40
  and  
2/5
=
16/40
Since the equivalent fractions have common denominators, we can compare the numerators:
15 is less than 16  (15 < 16)
As a result,  
15/40
  is less than
16/40
Therefore,  
3/8
  is less than
2/5
,  
3/8
<
2/5
