What is 5 sevenths minus 3 fifths?

To subtract ( \frac{3}{5} ) from ( \frac{5}{7} ), we first need a common denominator. The least common multiple of 7 and 5 is 35. Converting the fractions, ( \frac{5}{7} = \frac{25}{35} ) and ( \frac{3}{5} = \frac{21}{35} ). Now, subtracting these gives ( \frac{25}{35} - \frac{21}{35} = \frac{4}{35} ). Thus, ( \frac{5}{7} - \frac{3}{5} = \frac{4}{35} ).
