When you multiply decimals, you just ignore the decimal until the end, then, to find the amount of decimal places in your answer, you add the amount of decimal places in both your factors
Theoretically, if we are concerning decimal numbers, a decimal number can have an infinite number of decimal factors.
It is not clear where the factors came from!
The question "What goes into a number?" is asking about factors. Factors refer to integers, not decimals. Any decimal can go into any other decimal with a decimal result. It's meaningless.
For a number to have common factors, there needs to be another number to compare its factors with.
For common factors to exist, there needs to be one or more numbers to compare the factors of.
For common factors to exist, there need to be more than one number to compare the factors.
The number of decimal places in the product must equal the total number of decimal places in the factors. John's product should have 2 decimal places.
Two of them.
They both create an ecosystem.
The number of decimal places for the product will be the summation of the amount of decimal places of the 2 factors. For example, if your products have 2 decimals each to the right of zero then the product will have an answer with 4 decimals to the right of zero.
Common factors are used to compare two or more numbers. A single number cannot have common factors.
