4/7 - 2/5 = 6/35.
To subtract (or add) fractions make both fractions equivalent fractions with the same denominator. The LCM (Lowest Common Multiple) of 7 and 5 is 35, so convert both the fractions to equivalent fractions out of 35:
4/7 = 20/35
2/5 = 14/35
The subtraction can now be done:
4/7 - 2/5 = 20/35 - 14/35 = 6/35
