Answer 2

To simplify the expression -2.5 × (-2 2/5) × (4 4/9) × 8 5/5, let's break it down step by step:

Step 1: Convert mixed numbers to improper fractions: -2 2/5 = (-2 × 5 + 2) / 5 = -12/5 4 4/9 = (4 × 9 + 4) / 9 = 40/9 8 5/5 = (8 × 5 + 5) / 5 = 45/5

Step 2: Multiply the fractions: -2.5 × (-12/5) × (40/9) × (45/5)

Step 3: Simplify the fractions and decimals: -2.5 is the same as -5/2 -5/2 × -12/5 × 40/9 × 45/5

The negative signs cancel each other out, so we can ignore them for now.

Step 4: Multiply the numerators together and multiply the denominators together: (5 × 12 × 40 × 45) / (2 × 5 × 9 × 5)

Step 5: Simplify the fraction by canceling out common factors: (3 × 4 × 2 × 45) / (2 × 3 × 3 × 5) (4 × 45) / (3 × 5)

Step 6: Multiply the remaining numbers together: 180 / 15 = 12

Step 7: Reintroduce the negative sign: Since we ignored the negative signs earlier, we need to reintroduce them now. Since there were two negative signs, the final result is negative.

Final Result: -12
