To simplify the expression 12 8/15 - 7 + 7/15 + 15, we first need to convert all the mixed numbers to improper fractions.
12 8/15 = (15 * 12 + 8) / 15 = 160/15
7 = 7/1
7/15 = 7/15
15 = 15/1
Now we can add all the fractions:
160/15 - 7/1 + 7/15 + 15/1
To add fractions, we need to have a common denominator. In this case, the common denominator is 15.
160/15 - 7/1 + 7/15 + 15/1
Now we can rewrite each fraction with the common denominator:
(160 - 7 * 15 + 7 + 15 * 15) / 15
Simplifying further:
(160 - 105 + 7 + 225) / 15
(287 + 232) / 15
519 / 15
So the simplified answer is 34 9/15
