Christina collects stamps. She has 47 stamps in all. She has 20 stamps from Europe. The number of African stamps is 2 times the number of Asian stamps. How many stamps from each of these three continents does she have?

47-20=27 from the two continents
27/3=9, the ratio is 2:1 so there is 3 in total
2*9=18= African
1*9=9= Asian 
20=European
