"Numbers Separated by Colons"- Sequel

Hi,
I could use some clarification about the foll :

> C full diminished seventh (192:225:270:320)=(4*16/15:5:6:4*16/9):
> Cdim7: C (4/5) D# (15/8) F# (9/8) A (4/3)
>
I do not understand how one arrives at those figures.
Since the chord in question is a stack of minor 2nds,(using 6/5s) - 6/5,
36/25, 216/125.
How does one go about notating these in colon form ?

>The values line up as follows:
>
> note name whole number small (possibly fractional) number
> --------- ------------
----------------------------------
> C 192 4*16/15 (= 64/15)
> D# 225 5
> F# 270 6
> A 320 4*16/9 (= 64/9)

How do these single large no.s represent those notes ?

Thanks in advance.
