What does '100%' on an answer mean?

what does it meen if you have a 100.0% over your answer to a question?

It basically means that at least one person thinks your answer was helpful, see the link underneath the answer saying did you find this helpful. Click yes if you think it is.

The 100% is from when you could decide whether it was helpful . . . . or not. You would get the prcentage of people who found it helpful.

It means a user on FunAdvice found your answer helpful,if you look at other users ratings and rated more than 4 times,it changes from 100% to 80% or more,depending on how helpful people find it.

See how under each answer it says

Did you find this answer helpful? Yes Report abuse

When people like your answer and it was helpful to them, they click on the yes and it shows 100%.

It means a user on FunAdvice found your answer helpful,if you look at other users ratings and rated more than 4 times,it changes from 100% to 80% or more,depending on how helpful people find it.

uhm not quite... the 80% is left over from the days where we had an option to mark an answer as unhelpful... so if 1 person found it helpful, but 1 did not, it would give you a 50%, if 4 found it helpful, but 1 did not, it would give you an 80% etc etc...
