Canada has a population that is about one-tenth as large as the United States Canada and the population is about 32 million about how many people live in the United States explain the number of zeros in your answer

32 million is

32,000,000 - - Remember, a million has 6 zeroes: 1,000,000. So 32 of those would be 32,000,000.

10 times that is the same as "adding another zero." But don't literally do that! Because if you added another zero, you'd get 32million plus zero--that's still 32 million.

What we mean by adding a zero is adding a zero to the end of the number--since anything multiplied by 10 has this property. Thus, the answer is 320,000,000. You can see this number has one more zero than 32 million. The number of zeros is 7.
