Explanation:

Step1: Find common denominator

Rewrite $\frac{3}{5}$ with denominator 10:
$\frac{3}{5} = \frac{3\times2}{5\times2} = \frac{6}{10}$

Step2: Subtract the fractions

Subtract the numerators over common denominator:
$\frac{6}{10} - \frac{2}{10} = \frac{6-2}{10} = \frac{4}{10}$

Step3: Simplify the fraction

Reduce to lowest terms by dividing numerator and denominator by 2:
$\frac{4\div2}{10\div2} = \frac{2}{5}$

Answer:

$\frac{2}{5}$
