To find the fraction of the paint that Mark used, we can express it in relation to the amount of paint he originally had.

1. **Amount of paint Mark originally had:** \( \frac{3}{2} \) cans
2. **Amount of paint used:** \( \frac{1}{2} \) can

To find the fraction of paint used, we can divide the amount of paint used by the amount he originally had:

\[
\text{Fraction used} = \frac{\text{Amount used}}{\text{Amount originally had}} = \frac{\frac{1}{2}}{\frac{3}{2}}
\]

When dividing fractions, we multiply by the reciprocal:

\[
\frac{1}{2} \div \frac{3}{2} = \frac{1}{2} \times \frac{2}{3} = \frac{1 \times 2}{2 \times 3} = \frac{2}{6} = \frac{1}{3}
\]

Thus, the fraction of paint that Mark used is \( \frac{1}{3} \).

The correct answer is \( \frac{1}{3} \).
