Find how much meat was cooked, then subtract from the total.<br><br>
&bull; Amount cooked = \( \frac{2}{3} \) of \( \frac{1}{2} \) kg = \( \frac{2}{3} \times \frac{1}{2} = \frac{2}{6} = \frac{1}{3} \) kg<br>
&bull; Amount left = \( \frac{1}{2} - \frac{1}{3} \)<br>
&bull; Common denominator of 6: \( \frac{3}{6} - \frac{2}{6} = \frac{1}{6} \)<br><br>
Final Answer: \( \frac{1}{6} \) kg
