When working with mixed numbers, it is usually easier to convert them to improper fractions, do the operations, and then to convert any resulting improper fraction back to a mixed number:

5 3/8 + 7 5/6 = (5×8+3)/8 + (7×6+5)/6

= 43/8 + 47/6

= (43×3)/(8×3) + (47×4)/(6×4)

= 129/24 + 188/24

= 317/24

= (13×24+5)/24

= 13 5/24
