To subtract the fractions and decimals:

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

First, let's convert the mixed number 12 8/15 to a improper fraction:

12 8/15 = (12 * 15 + 8) / 15 = 188/15

Now, let's add all the fractions and decimals together:

188/15 - 7 + 7/15 + 15 = (188 - (7 * 15) + 7 + (15 * 15))/15

188 - (7 * 15) = 188 - 105 = 83

(83 + 7 + (15 * 15))/15 = (83 + 7 + 225)/15 = 315/15

Lastly, simplify the fraction:

315/15 = 21/1 = 21

Therefore, the simplified answer is 21.
