To determine the sign of a product, you need to consider the signs of the factors involved. Here's how you can solve each question:
1. For the product of 17/32 × (-1/10):
- Firstly, multiply the numerators together to get -17.
- Multiply the denominators together to get 320.
- The resulting fraction is -17/320.
- Since one factor is negative, the product is negative.
Therefore, the answer is A. negative.
2. For the product of -0.708 × -6.24:
- Multiply the absolute values together: 0.708 × 6.24 ≈ 4.42192.
- Since both factors are negative, the product is positive.
Therefore, the answer is A. positive.
3. For the product of -5 × -4:
- Multiply the absolute values together: 5 × 4 = 20.
- Since both factors are negative, the product is positive.
Therefore, the answer is A. 20.
4. For the product of 11 × -9:
- Multiply the absolute values together: 11 × 9 = 99.
- Since one factor is negative, the product is negative.
Therefore, the answer is A. -99.
5. The equation A × B = B × A represents the Commutative Property of Multiplication, which means the order of the numbers being multiplied does not affect the result.
Therefore, the correct answer is A. A × B = B × A.
