I'm confused i don't know what to do

1. What percentage of girls in Charlie's class would want a spider for a pet?
Ok, so 5 girls want a spider as a pet, and there are 30 kids in total in the class so 5/30 as a percentage is 56.66666667% so rounded thats 57%

2. What percentage of boys in Charlie's class would not want a spider for a pet?
So, there is 4 boys who dont want a spider as a pet and there are 30 people in the class so 4/30 is 13.33333333% so rounded that 13%

3. Supposed that 100 boys and 100 girls were asked if they would want a spider as a pet. based on the data how many would want a pet spider?
So, there are 17 in total who want a pet spider so 17/100 is 17% would want a pet spider.

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.

the answer is 18.
