Final answer:
The product of 3.72 and 4.06 will have 2 decimal places when considering only the decimal places and not the significant figures. option A is correct answer.
Step-by-step explanation:
The product of two numbers, each with a certain number of decimal places, will have a number of decimal places equal to the sum of the decimal places of the two original numbers. In this case, when multiplying 3.72 (two decimal places) by 4.06 (two decimal places), the resulting product will have a total of four decimal places.
However, in terms of significant figures, the final answer should have the same number of significant figures as the number with the least amount of significant figures used in the calculation. If only the decimal places are taken into account for the product, without considering significant figures, the correct answer for this question is 2 decimal places.
