An officer manager bought cases that each contained 12 reams of white paper. he also purchased 16 reams of different colored paper in all, how many cases of white paper did he buy?

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
