1. **State the problem:** Sami has 250 pumpkin seeds weighing a total of 0.2 kilograms. We need to find the weight of each seed in centigrams. 2. **Formula:** To find the weight per seed, use the formula: $$\text{weight per seed} = \frac{\text{total weight}}{\text{number of seeds}}$$ 3. **Convert units:** 0.2 kilograms must be converted to centigrams before dividing. - 1 kilogram = 1000 grams - 1 gram = 100 centigrams - Therefore, 1 kilogram = 1000 \times 100 = 100000 centigrams 4. **Convert 0.2 kilograms to centigrams:** $$0.2 \text{ kg} = 0.2 \times 100000 = 20000 \text{ centigrams}$$ 5. **Calculate weight per seed:** $$\text{weight per seed} = \frac{20000}{250}$$ 6. **Simplify the fraction:** $$\frac{20000}{250} = \frac{\cancel{20000}^{80} \times 250}{\cancel{250}} = 80$$ 7. **Answer:** Each seed weighs **80 centigrams**.
