Answer 2

To add these fractions together, you need to find a common denominator and then add the numerators.

The common denominator for 6, 9, 8, and 12 is 72. So, you need to rewrite each fraction with a denominator of 72:

• 5/6 can be rewritten as (5/6) * (12/12) = 60/72.
• -4/9 can be rewritten as (-4/9) * (8/8) = -32/72.
• -5/8 can be rewritten as (-5/8) * (9/9) = -45/72.
• 7/12 can be left as is since it already has a denominator of 12.

Now, you can add the fractions:

60/72 - 32/72 - 45/72 + 7/12

To add them, simply add the numerators together:

(60 - 32 - 45 + 42)/72

Now, calculate the numerator:

(60 - 32 - 45 + 42) = 25

So, the sum of the fractions is:

25/72
