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

x/0.8=6/1.5

Urgent!!

**Reiny**, Tuesday, September 11, 2012 at 9:01amThey 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
