Solve these problems. Use the U.S. standard algorithm to solve at least one of them.

  • 1 Enrique has a collection of stamps. He has 899 stamps from North America and 418 stamps from South America. If Enrique wants 1,500 stamps altogether, how many more stamps does he need?

  • 2 Ramona also has a stamp collection. She has 941 North American stamps and 483 European stamps. If Ramona wants 1,500 stamps altogether, how many more stamps does she need?

  • 3 Who has more stamps, Enrique or Ramona? How many more stamps?
