1. The problem asks: Carlos arranges 15 action figures in rows of 3. How many rows does Carlos make? 2. To find the number of rows, we use the division formula: $$\text{Number of rows} = \frac{\text{Total action figures}}{\text{Figures per row}}$$ 3. Substitute the values: $$\frac{15}{3}$$ 4. Perform the division: $$15 \div 3 = 5$$ 5. So, Carlos makes 5 rows. --- 6. Next, solve the addition problem: $$247 + 639$$ 7. Add the numbers: $$247 + 639 = 886$$ --- 8. Then, solve the subtraction problem: $$760 - 305$$ 9. Subtract the numbers: $$760 - 305 = 455$$ All calculations are correct as shown. Final answers: - Rows: 5 - Addition: 886 - Subtraction: 455
