Final answer:
The number 256.399 is not technically divisible by 97 because it's not a whole number. Similarly, it's not an exact product of 9 and another whole number factor.
Step-by-step explanation:
The question you are asking appears to be related to the divisibility of numbers and understanding factors. Let's clarify the initial statement: to determine whether 256.399 is divisible by 97, we need to divide 256.399 by 97 and see if the result is an integer without any remainder. Since 256.399 is not a whole number, it technically cannot be divisible by 97, but we can still discuss its division. Also, the part about the thumb seems irrelevant to the question.
If we are talking about the concept of a factor in multiplication, then saying that a number (let's call it X) is a product of 9 and another factor means that X = 9 × Y, where Y is the other factor. Unless we are dealing with an approximation or error in the given number due to a typo, 256.399 is not an exact product of 9 and another whole number factor. Therefore, based on the information provided, 256.399 is not divisible by 97 to result in an integer, and it is also not the product of 9 and another whole number factor.
