Question: A church has 120 members. 40% are adults. The rest are children. How many children more children are there than adults?
Answer: There are 48 adults because 120 x .4 = 48. 60% of members are children because 100 - 40 = 60. There are 72 children because 120 x .6 = 72. There are 24 more children than adults because 72 - 48 = 24. The answer is 24.
[Question]Patsy is gearing up for this weekend's graduation. She needs to have 6 appetizers per each of her 30 guests. She's making 3 dozen deviled eggs, 2 dozen pigs in a blanket and 2 dozen kebabs. How many more dozen appetizers does she need to make?
[Answer]She needs 6 appetizers per each of her 30 guests so she needs 6 * 30 = 180 appetizers. She's made 3 dozen deviled eggs, 2 dozen pigs in a blanket and 2 dozen kebabs so she's made 3 + 2 + 2 = 7 dozen appetizers. 7 dozen appetizers is 7 * 12 = 84 appetizers. She needs 180 appetizers and has made 84 so she needs 180 - 84 = 96 appetizers. 96 appetizers, in dozens, is 96 / 12 = 8 dozen more appetizers. The answer is 8.
Q: There's a Bobbit worm hiding in the bottom of James' aquarium. Every day it eats 2 fish. After two weeks, James adds 8 more fish to the aquarium. A week later, he discovers the Bobbit worm. If the aquarium had 60 fish to start with, how many does it have when James discovers the Bobbit worm?
A: First find the total number of weeks the Bobbit worm preys on the fish: 2 weeks + 1 week = 3 weeks. Then multiply that number by the number of days per week: 3 weeks * 7 days / week = 21 days. Then multiply that number by the number of fish the worm eats per day to find how many fish it eats total: 21 days * 2 fish / day = 42 fish. Then add the number of fish James adds to the starting number of fish to find the ending number of fish: 60 fish + 8 fish = 68 fish. Then subtract the number of eaten fish to find the number of surviving fish: 68 fish - 42 fish = 26 fish. The answer is 26.
Question: Hadassah took six hours to paint 12 paintings. What would be the total time she's taken to finish all the paintings if she paints 20 more paintings?
Answer: If it took Hadassah six hours to paint 12 paintings, then she paints 12 / 6 = 2 paintings in an hour. If two paintings take an hour to complete, 20 paintings will take 20 / 2 = 10 hours. The total time she took to finish all the paintings is 10 + 6 = 16 hours. The answer is 16.
