Each mixed number has to be converted to an improper fraction first. Then convert to common denominators.
= 8 5/6 - 2 4/9
convert to improper fractions
= 53/6 - 22/9
find common denominators; both denominators go into 18
= 159/18 - 44/18
subtract numerators
= 115/18
convert back to mixed number
= 6 7/18
ANSWER: 6 7/18
