Question: Ann is baking cookies. She bakes three dozen oatmeal raisin cookies, two dozen sugar cookies, and four dozen chocolate chip cookies. Ann gives away two dozen oatmeal raisin cookies, 1.5 dozen sugar cookies, and 2.5 dozen chocolate chip cookies. How many total cookies does she keep?
Answer: Ann had 3 dozen oatmeal cookies - 2 dozen = 1 dozen oatmeal cookies left. Ann had 2 dozen sugar cookies - 1.5 dozen = .5 dozen sugar cookies left. Ann had 4 dozen chocolate chip cookies - 2.5 dozen = 1.5 dozen chocolate chip cookies left. Ann has a total of 1 + .5 + 1.5 dozen cookies = 3 dozen cookies. 3 dozen cookies is 3 * 12 cookies = 36 cookies remaining. The answer is 36.

Question: There are six unicorns in the Enchanted Forest. Everywhere a unicorn steps, four flowers spring into bloom. The six unicorns are going to walk all the way across the forest side-by-side, a journey of 9 kilometers. If each unicorn moves 3 meters forward with each step, how many flowers bloom because of this trip?
Answer: First convert the total length of the journey from kilometers to meters: 9 kilometers * 1000 meters / kilometer = 9000 meters. Then divide this by the length of one step to find the number of steps in the journey: 9000 meters / 3 meters / step = 3000 steps. Then multiply the number of steps by the number of flowers per step to find how many flowers one unicorn creates on the journey: 3000 steps * 4 flowers / step = 12000 flowers. Then multiply the number of flowers per unicorn by the number of unicorns to find the total number of flowers created: 12000 flowers / unicorn * 6 unicorns = 72,000 flowers. The answer is 72000.

Question: If 24 out of every 60 individuals like football and out of those that like it, 50% play it, how many people would you expect play football out of a group of 250?
Answer: If 50% of individuals that like football play it, and there are 24 out of 60 individuals that like it, then 24 * 50% = 12 out of 60 individuals play it. If 12 individuals play it out of 60 individuals then that means only 12 / 60 = 1 / 5 or 20% play it. If 20% of individuals play football out of a group of 250 people, one would expect 250 * 20% = 50 individuals to play it. The answer is 50.

Question: Mary had 6 lambs and 2 of the lambs had 2 babies each. She traded 3 lambs for one goat. One morning, she woke up and found an extra 7 lambs in the field. How many lambs does Mary have?
Answer:
2 of her lambs had 2 babies each so that adds 2 * 2 = 4 lambs. She starts with 6 and adds 4 baby lambs so she had 6 + 4 = 10 lambs. She traded 3 of those lambs for a goat so she has 10 - 3 = 7 lambs. She has 7 and woke up to find 7 more lambs in the field so she has a total of 7 + 7 = 14 lambs. The answer is 14.
