Subtract 2/5 from 3/4.

Explanation:
When subtracting fractions with different denominators, rewrite both fractions so they share the same denominator, then subtract the numerators. For 3/4 and 2/5, a common denominator is 20. Convert 3/4 to 15/20 (multiply top and bottom by 5) and 2/5 to 8/20 (multiply top and bottom by 4). Now subtract the numerators: 15 − 8 = 7, with the common denominator 20, giving 7/20. This fraction is already in simplest terms, so the result is 7/20.
