Quizplus · Accepted Answer

To multiply a decimal and a negative decimal, we multiply normally and then give the product a negative sign. So 2.1 times -6.11 equals -12.831. Therefore, the best choice is D. When multiplying a positive number (2.1) by a negative number (-6.11), the result is always negative. To calculate the product, simply multiply the absolute values of the two numbers (2.1 times 6.11), which results in 12.831. Since the two original numbers have opposite signs, the final answer is negative. Therefore, the best choice is D, -12.831.
