If a is three times b, b is twice c, and c is four times d, what is the value of ?

a = 3b     therefore a = 3b = 6c = 24d

b = 2c                     b = 2c = 8d

c = 4d                     c = 4d

to determine a • c / b • d   let's put everything in terms of one "letter" ...  looks like d would be the easiest

24d • 4d              96d2

——–——    =    ———     the d2 cancel out leaving 96 divided by 8 which is 12

8d • d                 8d2

Same answer as the first guy, except I showed you how to get it.
