To determine how many puppets Jeri can make with 2/3 yard of fabric when each puppet requires 1/6 yard, we need to divide the total amount of fabric by the amount needed for each puppet.
We can perform the division as follows:
\[ \frac{2/3}{1/6} = \frac{2}{3} \times \frac{6}{1} = \frac{2 \times 6}{3 \times 1} = \frac{12}{3} = 4 \]
Jeri can make 4 puppets.
