1/2 is read half / one half / a half 1/3 is read one third / a third 1/4 is read one fourth / a fourth / one quarter / a quarter For the 1/5, 1/6, etc., we read "one" or "a" followed by the ordinal number: a fifth, a sixth, etc. Lots of luck pronouncing the final Th sounds after another consonant or consonant cluster :D

In mathematics "one third" In any other context "one out of three"

One-third!!! Hope this should be a better way to express the right one to many others!

A third.

"one third"
