8. 460 mL = _______ L – 0.46 L 1.4 km = _______ m – 1,400 m 2,456 cL = _______ L – 24.56 L 0.3 Dg = _______ mg – 3,000 mg

9. 72 cups = _______ pints – 36 pints 53 pints = _______ cups – 106 cups 170 pints = _______ quarts – 85 quarts 106 quarts = _______ pints – 212 pints 8 gallons = _______ quarts – 32 quarts 124 quarts = _______ gallons – 31 gallons

10. 16 cups = _______ quarts – 4 quarts 5 gallons = _______ pints – 40 pints 12 cups = _______ gallons – ¾ of a gallon 3 pints = _______ quarts – 1 and ½ quarts

11. **REMEMBER TO SIMPLIFY** 2 gal 4 pints + 14 pints – 20 pints + 14 pints = 34 pints = 4 gal 2 pints – 4 gal 1 quart 5 quarts 10 cups + 4 pints – 5 quarts 5 pints + 4 pints = 5 quarts 9 pints = 9 quarts 1 pint – 1 gal 1 quart 1 pint

12. A maple syrup manufacturer ships his product in bottles which each hold 8 cups of syrup. If each shipping box contains 144 bottles, how many gallons of syrup are in each box? – 8 X 144 = 1,152 cups  1,152 ÷ 16 = 72 gal A driveway contractor uses approximately 2,750 kg of concrete in each driveway he builds. How many grams of concrete is this? One week he constructed 7 new driveways, how many grams of concrete was used in all? – 2,750,000 g; 7 X 2,750,000 = 19,250,000 g

13. On average, the star running back on the football team ran 1,640 yards per season. If his career lasted for 11 seasons, how many miles did he run over his entire career? – 1,640 X 11 = 18,040  18,040 ÷ 1,760 = 10.25 mi If one paperclip has the mass of 1 gram and 1,000 paperclips have a mass of 1 kilogram, how many kilograms are 8,000 paperclips? – 8,000 paperclips = 8,000 g = 8 kg
