Answer

a.) 18 qt b.) 0.75 lb

Work Step by Step

a.) 4 1/2 gal = 18 qt You are converting from a larger unit to a smaller unit (a gallon is larger than a quart), so multiply. Because 1 gal = 4 quarts, multiply by 4. 4 1/2 gal= 9/2 * 4/1 = 18 qt b.) 12 oz = 3/4 lb = 0.75 lb You are converting from a smaller unit to a larger unit (a ounce is smaller than a pound) so divide. Because 16 ounces (oz) = 1 pound (lb), divide by 16. 12 oz = 12 / 16 = ¾ or 0.75 lb
