What is three fifths minus two tenths?

Three-fifths (3/5) minus two-tenths (2/10) can be calculated by first converting two-tenths to fifths. Since 2/10 is equivalent to 1/5, we can rewrite the expression as 3/5 - 1/5. This simplifies to 2/5. Therefore, three-fifths minus two-tenths equals two-fifths (2/5).
