Can a/b and (a+b)/b ever form a proportion? Why or why not?

  • MA -

    well, let's try it ...

    a/b = (a+b)/b
    times b, if b ≠0

    a = a+b
    then b = 0
    but now we have a contraction, so .....

    or

    cross - multiply
    ab = ab + b^2
    b^2 = 0
    b = 0 , but that would make a/b undefined,

    so what do you think?
