Final answer:

To estimate the product of 11.9 x 21, we round 11.9 to 12 and multiply it by 21, giving us an estimated product of 252. Among the options, the closest estimate is 250.

Step-by-step explanation:

To estimate the product of 11.9 x 21, we can round the numbers to their nearest whole numbers and then multiply. Here's how we can do it step-by-step:

  1. Round 11.9 to the nearest whole number, which is 12.
  2. 21 is already a whole number, so we keep it as is.

  4. The estimated product is 252.

Among the given options, the closest to our estimated answer is option b, 250. Therefore, the estimated answer for the product of 11.9 x 21 is approximately 250.
