Well, it makes sense if 1 is 2, for example, then 2 would be 4, so an example of this would be 4:2, and 2 is half of 4. Sorry, I'm not really good with ratios, but I think my answer makes sense. Please double check for me, thanks! :)
41.803 is 42 rounded to the nearest whole number because when you go past .5 you round to the nearest highest number, but when your below .5 then you round to the nearest lowest number.
