No because if you do math then it would be a decimal number and a decimal number isn't considered a multiple number. The last number has to be a 5 or 0 to be a multiple by 5.
no,
you can see this by dividing 552 by 5, you will get 110.4. If this number were an integer (i.e and whole number like 2, 3, 4 ect) then it would be a multiple.
An example of multiples of 5 are 10, 50, and 555. try dividing these numbers buy 5 and you will see that you will get integers.
