How to accommodate a fraction? (7)
I believe the answer is:
quarter
This clue is a double definition.
'how to accommodate' is the first definition.
(I know that quarter is a more specific form of the action accommodate)
'a fraction?' is the second definition.
(I know that quarter is a more specific form of the action fraction)
(Other definitions for quarter that I've seen before include "See 17 Across" , "Clemency" , "Divide into four" , "Area of town; mercy" , "A small piece" .)
