Eighteen out of 25 teens said they eat breakfast every morning. What is a reasonable prediction for the number of teens out of 1500 who eat breakfast every morning?

1/4 because there is 4 grades.

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.

so, converting firstly the mixed fractions to improper fractions and then "adding".
