Most would think by adding them all together you can can get the closest number,but then the simplest way is 1 sixth plus 3 fifths plus 4 fifteenths gets you 31 over 30 which gets you to 1.03 reoccurring and would stop there.
Instead i went further and found bring it all to the denominator of 60:
3 fifths
plus
3 twentieths
plus
4 fifteenths
equals
61 over 60 then when divided equals 1.016 reoccurring.

Making it roughly 0.014 gap between them.
