Question

in a multiplication problem, if the first factor has 5 digits after the decimal and the second factor has 4 digits after the decimal, then the product will have _____ digits after the decimal.

Answer 1

9 digits after the decimal because 5+4=9

Answer 2

The answer is nine digits. For a clear explanation, in a math problem with decimals, we count the number of numbers behind the decimal. In this case, there is 5 and 4 digits behind it, so we add those so, which gives us nine. Hope this helps. Good luck!
