    Got a little problem which looks easy but can't seem to grasp the answer, any help will be much appreciated!

    \frac{\Delta A}{A}=\frac{\Delta B}{B}=\alpha

    Where \alpha is a known constant and all other values are unknown


    If anyone can provide me step from getting from line 1 to line 2 you will make my day! Thanks in advance

    This isn't true for all A,B, etc. e.g. if \frac{6}{3}=\frac{4}{2}=2 then 3\times 2 \neq  1+2.

    What do all the variables mean?
