To find out how many pounds of salt each cook would get if 3 cooks shared \( \frac{2}{3} \) of a pound of salt equally, you need to divide \( \frac{2}{3} \) by 3.
This can be expressed as:
\[ \frac{2}{3} \div 3 = \frac{2}{3} \div \frac{3}{1} = \frac{2}{3} \times \frac{1}{3} = \frac{2 \times 1}{3 \times 3} = \frac{2}{9} \]
So, each cook would get \( \frac{2}{9} \) of a pound of salt. The answer is:
\(\frac{2}{9}\) of a pound of salt.
