When is the product of a decimal numbers n x 10 always a whole number?
The product of a decimal number ( n ) and 10 is always a whole number when ( n ) has only one decimal place. This is because multiplying a decimal with one decimal place (e.g., 2.5) by 10 shifts the decimal point one place to the right, resulting in a whole number (e.g., 25). If ( n ) has more than one decimal place, the product will not be a whole number.
