Question

Help if you can, thank you ;)

Answer 1

b =
`(3)/(8)` a

Explanation:

Since I do not know which variable is the dependent and which variable is the independent, the equation could be written in two ways.

b =
`(3)/(8)` a

or

a =
`(8)/(3)`b

Since we are told that the relationship is proportional. The constant of proportionality would be the dependent value over the dependent value.
