Maria conflicted about a decimal (7,8)

I believe the answer is:

decimal fraction

'a decimal' is the definition.
('decimal fraction' can be a synonym of 'decimal')

'maria conflicted about' is the wordplay.
'about' indicates anagramming the letters.
'maria'+'conflicted'='mariaconflicted'
'mariaconflicted' is an anagram of 'DECIMAL FRACTION'.
