triciaal
2 3/8  + 1 3/4  + 5 7/8
one approach
separate whole numbers (2 + 1 + 5 ) and fractions (3/8 + 3/4 + 7/8)
find the lowest common denominator of the fractions, (8) simplify  ( 3 + 6 + 7) /8 change to mixed number if necessary (16/8 = 2)
Add the whole number to the mixed number  8 + 2 = 10 
 
2 3/8  + 1 3/4  + 5 7/8 = 10
