Answer 2

Let's simplify the expression step by step:

1. Simplify the subtraction inside the parentheses: 80 - 2 - 80 and 1/6 can be combined: 80 - 2 - 80 + 1/6

2. Perform the arithmetic operation inside the parentheses: (80 - 82) + 1/6

3. Perform the subtraction inside the parentheses: -2 + 1/6

4. Find the common denominator to combine the fractions: (-2 * 6 + 1) / 6 (-12 + 1) / 6 (-11) / 6

5. Now, let's multiply the result by 3/13: ((-11) / 6) * (3/13)

6. Multiply the numerators and denominators separately: (-11 * 3) / (6 * 13)

7. Calculate the numerator and denominator: -33 / 78

8. Simplify the fraction, if possible: -11 / 26

So, the simplified result of the expression is -11/26.
