Final answer:

To estimate the value of the given expression, round the numbers and perform the calculations.

Explanation:

To estimate the value of 39.3 x 2.1 / 18.5, we can round the numbers to more manageable values. Let's round 39.3 to 40, 2.1 to 2, and 18.5 to 20. Now, we can find the estimated value by dividing 40 x 2 and then dividing the result by 20.

  1. 40 x 2 = 80
  2. 80 / 20 = 4

So, the estimated value of 39.3 x 2.1 / 18.5 is approximately 4.
