1. **Problem 2:** A large ship was loaded with 20 tons of grain and 5 tons of flour. We need to find how many more pounds of grain there were on the ship. 2. **Formula and conversion:** 1 ton = 2000 pounds. 3. **Calculate pounds of grain:** $$20 \text{ tons} \times 2000 \frac{\text{pounds}}{\text{ton}} = 40000 \text{ pounds}$$ 4. **Calculate pounds of flour:** $$5 \text{ tons} \times 2000 \frac{\text{pounds}}{\text{ton}} = 10000 \text{ pounds}$$ 5. **Find how many more pounds of grain than flour:** $$40000 - 10000 = 30000 \text{ pounds}$$ --- 6. **Problem 3:** Largest wheel of cheese in City A weighs 985 pounds, City B weighs 894 pounds. Find total ounces. 7. **Formula and conversion:** 1 pound = 16 ounces. 8. **Calculate total pounds:** $$985 + 894 = 1879 \text{ pounds}$$ 9. **Convert total pounds to ounces:** $$1879 \times 16 = 30064 \text{ ounces}$$ --- 10. **Problem 4:** Tito stored 15 gallons, Jack stored 29 gallons, total 44 gallons. They used 32 gallons. Find quarts left. 11. **Calculate gallons left:** $$44 - 32 = 12 \text{ gallons}$$ 12. **Formula and conversion:** 1 gallon = 4 quarts. 13. **Convert gallons left to quarts:** $$12 \times 4 = 48 \text{ quarts}$$ --- 14. **Problem 5:** Large airplane 5 tons, medium 3 tons, small 1544 pounds. Find total pounds. 15. **Convert tons to pounds:** $$5 \times 2000 = 10000 \text{ pounds}$$ $$3 \times 2000 = 6000 \text{ pounds}$$ 16. **Add all pounds:** $$10000 + 6000 + 1544 = 17544 \text{ pounds}$$ **Final answers:** - Problem 2: 30000 pounds more grain. - Problem 3: 30064 ounces total. - Problem 4: 48 quarts left. - Problem 5: 17544 pounds total luggage.
