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 can be written as (12*15 + 8)/15 = 188/15.
7 can be written as 7/1.
7/15 remains as 7/15.
15 can be written as 15/1.
Now that everything is in fraction form, we can add and subtract:
188/15 - 7/1 + 7/15 + 15/1
To add or subtract fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 15.
(188 - 7*15 + 7 + 15)/15
(188 - 105 + 7 + 15)/15
(192)/15
The simplified answer is 12 12/15, which can be further simplified to 13 2/5.
Therefore, the answer is 13 2/5.
