If you want to do it by hand, you might find it convenient to add the integer and fractional parts separately.
(8 1/3) +(8 5/6) +(2 3/8) +(2 1/2)
= (8 +8 +2 +2) + (1/3 +5/6 +3/8 +1/2)
= 20 +(2/6 +5/6) +(3/8 +4/8) . . . . . . use simple LCDs to combine pairs
= 20 +7/6 +7/8
= 21 + (1/6 +7/8) . . . . . simplify back to proper fractions
= 21 +(4/24 +21/24) = 21 +25/24 . . . . . use LCD = 24 for denominators 6, 8
= 22 1/24
