Im doing some online tests and seem to keep getting my ratio expressions wrong,

Example:

QUESTION

What is the ratio of the number of tornados in 2008 to those in 2005?

A) 1.36:1 B) 1:1.28 C) 0.78:1 D)1.26:1

Answer:

Jets in 2008 = 297

Jets in 2005 = 380

279:380 = 1:1.28

However correct answer is 0.78:1 - why?

Why does it matter whether you express it as "one to..." or "...to one"?

Arent both expressions the same?

If someone could clarify this for me id appreciate it, thanks.
