According to the division property of equality, "when both sides of an equation are divided by the same non-zero number, the two sides remain equal".
Thus, when we divide the number of shapes in each pans by a 2, we have
[tex]\begin{gathered} \text{Left pan:} \\ \frac{number\text{ of shapes}}{2}=\frac{2}{2}=1 \end{gathered}[/tex][tex]\begin{gathered} \text{Right pan:} \\ \frac{\text{number of shapes}}{2}=\frac{6}{2}=3 \end{gathered}[/tex]
Thus, the left pan has its number of shapes equal to 1
