The point claimed to be misrepresented? (7)
I believe the answer is:
decimal
'the point' is the definition.
(I have seen 'The point' mean 'decimal' so perhaps 'point' could also mean 'decimal')
'claimed to be misrepresented?' is the wordplay.
'to be misrepresented?' indicates an anagram.
'claimed' anagrammed gives 'DECIMAL'.
(Other definitions for decimal that I've seen before include "Medical (anag.)" , "System based on ten" , "Claimed (anag) - a point" , "A point in maths" , "Relating to ten" .)
