How is the twenty-four inch gauge divided?

• A. Into twelve equal parts.
• B. Into six equal parts.
• C. Into three equal parts.
• D. Into Twenty-Four Equal Parts.

Answer: (D)

Think of the 24-inch gauge as a ruler that is 24 inches long. Its natural divisions are into 24 equal parts because that matches the total length exactly and lets you read every inch easily. Each division represents one inch, so you can measure any length from 0 up to 24 inches by counting those divisions. Dividing into 12 parts would make each segment two inches long, which doesn’t align with the inch marks on the tool, and dividing into 6 or 3 parts would lump many inches together. The straightforward, consistent subdivision for a 24-inch length is into twenty-four equal parts.
