To find the width of each stamp, we first need to determine the total width occupied by the 7 stamps. The overall width of the frame is 6 inches. Assuming that the 7 stamps fit perfectly across the frame and there are no gaps between them, we can find the width of each stamp by dividing the total width of the frame by the number of stamps.
We can calculate the width of each stamp using the following formula:
\[ \text{Width of each stamp} = \frac{\text{Total width of the frame}}{\text{Number of stamps}} = \frac{6 \text{ inches}}{7} \]
Thus, the width of each stamp is
\[ \frac{6}{7} \text{ inches}. \]
So, the width of each stamp is \(\frac{6}{7}\) inches.
