Is 21 a multiple of 0?
Here we will illustrate two ways to figure out if 21 is a multiple of 0.
One way would be to list all of the multiples of 0 and check if 21 is one of the numbers.
Multiples of 0 are 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 and so on.
Since 21 is not on the list of multiples of 0, the answer to the question "Is 21 a multiple of 0?" is: No.
Another way, would be to simply divide 21 by 0. If the result is a positive integer, then 21 is a multiple of 0.
21 divided by 0 equals 0, which is not a positive integer. Once again, the answer to our question is: No.
