To determine the width of the widest stamp from the measurements provided, we need to convert all measurements to the same unit. The widths given are:
- 158 inches
- 11116 inches
- 134 inches
- 112 inches
Comparing the measurements directly:
- 158 inches
- 11116 inches
- 134 inches
- 112 inches
To identify which ones appear to be in a different unit, note that 11116 looks unusual. This number does not seem plausible for a stamp measurement in inches.
However, looking closely, it can be interpreted as 111/16 inches, which is a way to write a fraction. To convert this to a decimal or a simpler fraction:
\[ 111/16 = 6.9375 \text{ inches} \]
Now, let's summarize all the measurements in inches for comparison:
- 158 inches
- \( 6.9375 \) inches (converting \( 111/16 \) inches)
- 134 inches
- 112 inches
Now, we can clearly see the values:
- 158 inches
- Approximately 6.94 inches
- 134 inches
- 112 inches
The widest stamp measured is clearly \( 158 \) inches.
Thus, the width of the widest stamp is:
\[ \boxed{158 \text{ inches}} \]
