To subtract fractions, they must have a common denominator. The least common denominator (LCD) of 5 and 15 is 15. Convert $\frac{3}{5}$ to a fraction with a denominator of 15 by multiplying both the numerator and denominator by 3, resulting in $\frac{9}{15}$. The subtraction is then $\frac{9}{15} - \frac{1}{15} = \frac{8}{15}$.
