Final answer:
The length of the world's longest beard in meters is calculated by setting up a proportion and using the conversion rate of 1 meter to 3.28 feet. After converting 9 inches to 0.75 feet and adding it to the 7 feet, we find that the beard length of 7.75 feet is approximately 2.36 meters.
Step-by-step explanation:
To find the length of the longest beard in meters, we can set up a proportion using the given information that 1 meter equals 3.28 feet. The man's beard is 7 feet 9 inches long. First, convert the inches to feet by dividing by 12 (9 inches / 12 inches per foot = 0.75 feet). This gives us a total length of 7.75 feet (7 feet + 0.75 feet).
Now, we can create the proportion:
- 1 meter / 3.28 feet = x meters / 7.75 feet
To solve for x, cross-multiply and divide:
- (1 meter * 7.75 feet) / 3.28 feet = x meters
- 7.75 meters / 3.28 = x meters
- x ≈ 2.36 meters
Therefore, the length of the beard in meters is approximately 2.36 meters.
