Katie collects stamps. She has stamps from Canada, the United States, and the rest of the world in a ratio of 1:1.2:1.5. She has 135 stamps from the rest of the world.

How many stamps are from Canada?

How many stamps are from the United States?

What is the total number of stamps in Katie’s collection?

1 is 2/3 of of 1.5          2/3 * 135   = 90 stamps from Canada

1.2 / 1.5 * 135 = 108 from US

135 + 90 + 108 = ....... total stamps

1:1.2:1.5 = 90: 108: 135
