Question: Carla's sheepdog rounded up 90% of her sheep, but the remaining 10% wandered off into the hills. If there are 81 sheep in the pen, how many are out in the wilderness?
Answer: First find the total number of sheep by dividing the number rounded up by 90%: 81 sheep / .9 = 90 sheep. Then multiply that number by 10% to find the number that are in the hills: 90 sheep * 10% = 9 sheep. The answer is 9.
[Question]Janet makes 50 snowballs and her brother makes 150 snowballs. What percentage of the snowballs did Janet make?
[Answer]First add the number of snowballs each person made to find the total: 50 snowballs + 150 snowballs = 200 snowballs. Then divide the number Janet made by the total number and multiply by 100% to express the answer as a percentage: 50 snowballs / 200 snowballs * 100% = 25%. The answer is 25.
Q: James turned 23 the same time John turned 35. Tim is 5 years less than twice John's age. If Tim is 79 how old is James?
A: James is 35 - 23 = 12 years younger than John. 5 years less than Tim's age is 79 - 5 = 74 years old. So John is 74 / 2 = 37 years old. That means James is 37 - 12 = 25 years old. The answer is 25.
Question: Frank bakes two trays of cookies per day, for 6 days. Frank eats one cookie each day to make sure they taste good. Ted comes over on the sixth day and eats 4 cookies. If each tray makes 12 cookies, how many cookies are left when Ted leaves?
Answer: Frank bakes 2 * 12 = 24 cookies per day. Frank bakes a total of 24 * 6 = 144 cookies. Frank eats 1 * 6 = 6 cookies. After Ted leaves, there are 144 - 6 - 4 = 134. The answer is 134.
