Answer: The product of 3.41 and 8.5 will have 3 decimal places.
Step-by-step explanation:
The Rule to Multiplying Decimals:
1) Multiply all the numbers(in other words, ignore the decimals)
2) When you get the finished product, count the decimal numbers in the problem(the numbers that are behind decimals)
3) Count over the decimal number in the answer.
Example: The product of 3.41 and 8.5 without the decimals is 28,985. There are 3 decimal numbers(3.41 and 8.5). So, you would count the decimal over 3 times in the answer. Your final answer is 28.985.
Please correct me if I'm wrong! :D
