Answer 2

To add fractions with different denominators, you need to find a common denominator. In this case, the common denominator for 12 and 9 is 36.

First, let's convert 5/12 to an equivalent fraction with a denominator of 36: (5/12) * (3/3) = 15/36

Now, let's convert -7/9 to an equivalent fraction with a denominator of 36: (-7/9) * (4/4) = -28/36

Now that both fractions have the same denominator, we can add them: 15/36 + (-28/36)

To add the fractions, you simply add the numerators while keeping the denominator the same: (15 - 28) / 36 = -13/36

Therefore, 5/12 + (-7/9) equals -13/36.
