Kevin told Marcus that when you multiply any number by 103, you can just write three zeroes after the last digit of the number. He gives an example of 5 x 103 = 5000 to help show that his rule is correct. Marcus disagrees and says that the product 0.5 x 103 shows that Kevin's rule is not always true.
Who is correct? Explain why.
Marcus is correct because 0.5 x 103 = 500. The place value shifted three times, but 500 only has two zeroes in it.
