Answer 2

12 + 2/5 - (7 + 11/15 + 2 + 8/15)

First, we need to simplify the expression inside the parentheses: 7 + 2 = 9 11/15 + 8/15 = 19/15 So, the expression inside the parentheses becomes: 9 + 19/15

Now, we can subtract this expression from 12 + 2/5: 12 + 2/5 - (9 + 19/15)

To subtract the expression inside the parentheses, we need to find a common denominator for 2/5 and 19/15. The least common multiple of 5 and 15 is 15, so we can rewrite 2/5 as 6/15. Now, the expression becomes: 12 + 6/15 - 9 - 19/15

Combine the whole numbers: 12 - 9 = 3

Now, subtract the fractions: 6/15 - 19/15 = -13/15

So, the final answer is: 3 - 13/15 = 2 2/15
