x is to 6 as 0.8 is to 1.5
How do I write a proportion with that? (proportion such as eg. 14/105=x/315)
is it x/6=0.8/1.5 or is it

  • Math -

    They are both correct,
    notice that if you cross-multiply, you get
    1.5x = 6(.8) for both of them.

    That is always a good way to check.

    "x is to 6 as .8 is to 1.5 " is more obviously translated as
    x/6 = .8/1.5
