How do I report a ratio? I want to report a ratio in my thesis. The ratio is 16:84, but I also want tot report which number represents which class. Can I report that like this: 


  The data was not evenly distributed with a ratio of 16:84 (CN:AD). 


Or should I put the CN:AD in square brackets? And is it clear if I report it like this?  

UPDATE:
Now reported it as: 


  The data were unevenly distributed with a ratio CN:AD = 16:84. 


Thanks for the suggestions!
As pointed out by xLeitix, there aren't really any standards on this. Another possibly clearer way to report that ratio is:


  The data were not evenly distributed with a ratio CN:AD = 16:84.
