    Joe is 12 times taller than Bob

    No the answer not rely on the meaning of b

    Step-by-step explanation:

    * Lets explain how the solve the problem

    - The height of Bob is equal to b cm

    - The height of Bob is 8/9 of the height of Bill

    - Because 8/9 is less than one, then Bob is shorter than Bill

    - The height of Bill makes up 3/32 of the height of Joe

    * Lets write these information by mathematics relation

    ∵ The height of Bob is b

    ∵ The height of Bob is 8/9 height of Bill

    ∴ b = 8/9 the height of Bill

    - Multiply both sides by 9

    ∴ 9 b = 8 the height of Bill

    - Divide both sides by 8

    ∴ 9/8 b = the height of Bill

    ∴ The height of Bill is 9/8 b

    ∵ The height of Bill is 3/32 the height of Joe

    ∴ 9/8 b = 3/32 the height of Joe

    - Multiply both sides by 32

    ∴ 36 b = 3 the height of Joe

    - Divide both sides by 3

    ∴ 12 b = the height of Joe

    ∴ The height of Joe is 12 b

    ∵ b is the height of Bob

    ∴ The height of Joe is 12 times the height of Bob

    ∴ Joe is 12 times taller than Bob

    - NO, the answer doesn't depend on b because the ratio between the

    heights of Joe and Bob doesn't change by the change of b
