Answer: 1/3
Explanation:
To add fractions with different denominators, we first need to find a common denominator. In this case, the common denominator is 12.
11/12 + (-7/12) = (11 - 7) / 12
Simplifying the numerator gives us:
4/12
We can further simplify by dividing both the numerator and denominator by their greatest common factor, which is 4.
4/12 = 1/3
Therefore, 11/12 + (-7/12) = 1/3.
