Answer:

21 16/45

Explanation:

12 8/9 - 7 + 7/15 +15

concert mixed numbers to improper fractions

12 8/9 = 12 * 9 + 8 /9 so 116/9

add and subtract (left to right)

116/9 -7 = -7*9 /9 + 116/9

-7*9+116=53 so 53/9

53/9 + 7/15 = 286/45

286/45 + 15 = 961/45

convert improper fractions to mixed numbers

961/45 =21 remainder 16 so

21 16/45 is the answer
