Intelligence rating that results from division (8)
I believe the answer is:
quotient
This might be a double definition.
'intelligence rating' is the first definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'results from division' is the second definition.
The definition and answer can be both related to thinking as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'that' is the link.
Can you help me to learn more?
(Other definitions for quotient that I've seen before include "Three, when seven divided by two" , "The Q in IQ" , "Result obtained by division" , "rating?" , "Result of division (maths)" .)
