Answer 2

To solve the given mathematical expression, let's break it down step by step:

1. 7 - 27/11: To subtract a fraction from an integer, we need to find a common denominator. 7 can be written as 7/1. The common denominator for 1 and 11 is 11. Therefore, we have: (7/1) - (27/11) = (77/11) - (27/11) = (77 - 27)/11 = 50/11

2. 3 - 11/8: Again, we need to find a common denominator. 3 can be written as 3/1. The common denominator for 1 and 8 is 8. Therefore, we have: (3/1) - (11/8) = (24/8) - (11/8) = (24 - 11)/8 = 13/8

3. 2 + 6/11: We have an integer and a fraction, so no need to find a common denominator. 2 can be written as 2/1. Therefore, we have: (2/1) + (6/11) = (22/11) + (6/11) = (22 + 6)/11 = 28/11

4. 28/11 + 12/8: To add fractions, we need to find a common denominator. The common denominator for 11 and 8 is 88. Therefore, we have: (28/11) + (12/8) = (224/88) + (33/88) = (224 + 33)/88 = 257/88

So, the final result of the expression is 257/88.
