Is 15 a multiple of 90?

When you are asking the question "Is 15 a multiple of 90?", you want to know if 15 is one of the multiples of 90. Thus, to find the answer, we can look at all the multiples of 90 and see if one of them is 15. However, instead of making a long list of multiples, we will explain a fast and easy way to get the answer.

First, note that if we were to create a list of multiples of 90, we first multiply 90 by 1, then we multiply 90 by 2, then multiply 90 by 3, and so on indefinitely. In other words, 90 multiplied by any whole number is a multiple of 90. On the flip side, this means that any multiple of 90 divided by 90 will equal a whole number.

Therefore, you can check if 15 is a multiple of 90 by simply dividing 15 by 90. If the quotient is a whole number, then 15 is a multiple of 90.
