Answer 2

To simplify the expression (-31/3) × (-12/7) × (-3) × (-7), you can follow these steps:

1. Multiply the fractions: (-31/3) × (-12/7) = (31 * 12) / (3 * 7) = 372 / 21

2. Simplify the fraction: 372/21 simplifies to 18.

3. Now, you have the expression: 18 × (-3) × (-7)

4. Multiply the numbers: 18 × (-3) = -54

5. Finally, multiply by -7: -54 × (-7) = 378

So, the simplified expression is 378.
