Answer 2

Task Solution:

To solve Igor's task, we need to determine the number of stamps in his collection that are dedicated to cities around the world.

Given: - Total stamps in the collection: 450 - Proportion of stamps dedicated to different themes: - One third dedicated to space - Two fifths dedicated to cars - Remaining dedicated to cities around the world

Calculation:

Let's calculate the number of stamps dedicated to cities around the world: 1. Stamps dedicated to space: 450 * (1/3) = 150 2. Stamps dedicated to cars: 450 * (2/5) = 180 3. Total stamps dedicated to space and cars: 150 + 180 = 330 4. Stamps dedicated to cities around the world: 450 - 330 = 120

So, 120 stamps in Igor's collection are dedicated to cities around the world.

Therefore, Igor has 120 stamps in his collection that are dedicated to cities around the world.

Answer:

Igor has 120 stamps in his collection that are dedicated to cities around the world.
