Problem 5., Bojan and Zlatko have a certain number of stickers. Bojan has twice as many stickers as Mario, and Zlatko has twice as many stickers as Bojan. Zlatko and Mario together have 153 more stickers than Bojan. How many stickers does each of them have?
Solution. If the number of stickers Mario has is represented by one rectangle, then the number of stickers Bojan has is represented by 2, and Zlatko's by 4 rectangles.

Thus, the number of stickers that Mario and Zlatko have together is represented by 5 rectangles, so 1 rectangle corresponds to the number $153: 3=51$. According to this, Mario has 51 stickers, Bojan has $2 \cdot 51=102$ stickers, and Zlatko has $4 \cdot 51=204$ stickers.
