Lead height equals lead divided by height of the attachment. Which option expresses this correctly?

• A. Lead height equals height divided by lead
• B. Lead height equals the sum of lead and height
• C. Lead height equals height minus lead
• D. Lead height equals lead divided by height of the attachment

Answer: (A)

The main idea here is expressing a quantity as a ratio of two measurements. If lead height is defined as how much height there is per unit of lead, you write height divided by lead. That form captures the intended relationship: it shows how many units of height correspond to each unit of lead, which is what “lead height” is describing.

The other expressions don’t fit this idea. Adding or subtracting the quantities would describe a sum or difference rather than a ratio. Writing lead divided by height would describe lead per height, the reciprocal of the intended relationship, so it changes the meaning.
