Rješenje:
1. Neka je ukupni iznos koji Ivan ima 180 eura.
2. Potrošnja prvog dana:
- Prvi dan, Ivan potroši trećinu svojih sredstava:\frac{1}{3} \times 180 = 60
- Preostali iznos nakon prvog dana:180 - 60 = 120
3. Potrošnja drugog dana:
- Drugi dan, Ivan potroši 2/5 preostalog iznosa:\frac{2}{5} \times 120 = 48
- Preostali iznos nakon drugog dana:120 - 48 = 72
4. Potrošnja trećeg dana:
- Treći dan, Ivan potroši preostali iznos koji je: 72 eura.
Rješenje: Ivan je treći dan potrošio 72 eura.
