'three-quarters?' is the definition.
I can't judge whether this defines the answer.

'front-row forward for certain bashed' is the wordplay.
'front row forward' becomes 'prop' (I've seen this before).
'bashed' indicates an anagram.
'for'+'certain'='forcertain'
'forcertain' with letters rearranged gives 'erfraction'.
'prop'+'erfraction'='PROPER FRACTION'
