Which one of the following hose diameters is the largest?

To determine which hose diameter is the largest, we need to convert each option into a comparable format, either by converting the fractions to decimals or finding a common denominator.

1. The fraction 17/20 can be converted to a decimal by dividing 17 by 20, which equals 0.85 inches.
2. The fraction 3/4 can be converted by dividing 3 by 4, which gives 0.75 inches.
3. The fraction 3/5 results in 0.6 inches when 3 is divided by 5.
4. The fraction 8/10 simplifies to 0.8 inches when 8 is divided by 10.

Comparing these results:

• 0.85 inches (17/20)
• 0.75 inches (3/4)
• 0.6 inches (3/5)
• 0.8 inches (8/10)

From this comparison, it’s clear that 17/20 inches, or 0.85 inches, is the largest option provided. Knowing how to perform these conversions and comparisons is essential for understanding measurements in firefighting equipment, as pipe diameter can significantly affect water flow and pressure in firefighting situations.
