Use a property to explain why the product of a multiple of 10 and a number will have a zero in the ones place

It will have a zero at the end because if you have 30 skittles and then you multiply that by ten, you have only certain numbers to work with, remember, any number you multiply by zero, the product is zero. Good Luck!!
