Answer 2

To solve the expression 2 2/7x*(-0.125y)*3.5, we can follow the order of operations (also known as PEMDAS/BODMAS). Let's break it down step by step:

1. Convert the mixed number 2 2/7 to an improper fraction: 2 2/7 = (7 * 2 + 2)/7 = 16/7

2. Rewrite the expression with the improper fraction: (16/7)x*(-0.125y)*3.5

3. Multiply the fractions: (16/7) * (-0.125) = -2

4. Substitute the value of the expression: -2x*(-0.125y)*3.5

5. Multiply the remaining terms: -2 * x * (-0.125) * y * 3.5 = 0.875xy

Therefore, the simplified form of the expression 2 2/7x*(-0.125y)*3.5 is 0.875xy.
