Answer 2

Sure, I'd be happy to help you solve this expression step-by-step:

The expression is: -2 × (-1 1/3)² × 5.25

Step 1: Simplify the mixed fraction (-1 1/3) into an improper fraction: -1 1/3 = -1 - 1/3 = -4/3

Step 2: Square the improper fraction: (-4/3)² = (-4/3) × (-4/3) = 16/9

Step 3: Multiply the squared fraction by -2: -2 × 16/9 = -32/9

Step 4: Finally, multiply the result by 5.25: -32/9 × 5.25 = -168/9 = -56/3

So, the solution to the expression is -56/3. If you want to convert it to a mixed fraction, it would be approximately -18 2/3.
