what is 42 5/12 minus 27 7/12 equals

math 
Peter,
Basically 41 and 17/12 minus 27 and 7/12.
So it's 14 5/6

math 
Reiny,
42 5/12  27 7/12
= 509/12  331/12
= 178/12
= 89/6
= 14 5/6 , if you need a mixed number
but, mixed numbers are such useless numbers, since you cannot do anything with them
I would prefer the answer of 89/12
