I believe that the missing letter would be E and S which would be in between S and T
It already is in simplest form because the numerator and denonimator don't have a common factor to then divide them by.
I think it’s -36, not 100% sure though
I think it’s 3 not sure tho because i forgot most things about it
You have to find a common denominator 1st then add. So 16 is the common denominator the problem should be 2 7/16+1 14/16+8-16= 3 29/16 then you need to divide 29/16 you will have 4 13/16
