Question: Maria is chopping up vegetables for a stew. She wants to cut up six times as many carrots as potatoes, twice as many onions as carrots, and 1/3 as many green beans as onions. If she has two potatoes, how many green beans does she need to cut?
Answer: First find how many carrots Maria needs to cut by multiplying the number of potatoes by 6: 6 * 2 = 12. Then find how many onions she needs by multiplying the number of carrots by 2: 12 * 2 = 24. Finally, divide the number of onions by 3 to find the number of green beans she needs 24 / 3 = 8. The answer is 8.
[Question]Adam’s wardrobe is too crowded so he decides to donate some of his clothes to a charity shop. He takes out 4 pairs of pants, 4 jumpers, 4 pajama sets (top and bottom), and 20 t-shirts, then asks his friends if they have anything they want to donate. 3 of his friends donate the same amount of clothing as Adam each. Then he takes another look over his clothing and decides that he actually wants to keep half of his clothes. How many articles of clothing are being donated in total?
[Answer]As pajama sets are made up of a top and a bottom, there are 4 pajama sets * 2 = 8 articles of clothing from Adam's donation. In total, Adam is donating 4 pairs of pants + 4 jumpers + 8 pajama pieces + 20 t - shirts = 36 articles of clothing. Together, the 3 friends donate a total of 36 articles of clothing per friend * 3 friends = 108 articles of clothing. Adam changes his mind and takes back half, which means he is now actually donating 36 / 2 = 18 articles of clothing. There is therefore now a total of 108 + 18 = 126 articles of clothing being donated. The answer is 126.
Q: Sophie buys five cupcakes at $2 each, six doughnuts at $1 each, four slices of apple pie at $2 per slice, and fifteen cookies at $0.60 each. How much does she spend in all?
A: Five cupcakes cost 5 x $2 = $10. Six doughnuts cost 6 x $1 = $6. Four slices of apple pie cost 4 x $2 = $8. And, fifteen cookies cost 15 x $0.60 = $9. Therefore, Sophie spends $10 + $6 + $8 + $ 9 = $33. The answer is 33.
Question: Liza bought 10 kilograms of butter to make cookies. She used one-half of it for chocolate chip cookies, one-fifth of it for peanut butter cookies, and one-third of the remaining butter for sugar cookies. How many kilograms of butter are left after making those three kinds of cookies?
Answer: Liza used 10 / 2 = 5 kilograms of butter for the chocolate chip cookies. Then, she used 10 / 5 = 2 kilograms of butter for the peanut butter cookies. She used 5 + 2 = 7 kilograms of butter for the chocolate and peanut butter cookies. So, only 10 - 7 = 3 kilograms of butter was left. Then, Liza used 3 / 3 = 1 kilograms of butter for the sugar cookies. Therefore, only 3 - 1 = 2 kilograms of butter were left. The answer is 2.
[Question]John chops down 30 trees. From each tree, he can make 25 planks. A table takes 15 planks to make and sells for $300. He paid $3000 for all the labor. How much profit did he make?
[Answer]He got 30 * 25 = 750 planks. So he can make 750 / 15 = 50 tables. That means he makes 50 * 300 = $15000. So his profit was 15000 - 3000 = $12000. The answer is 12000.
[Question]A mountain range has 200 active volcanoes. In a particular year, 20% of the volcanoes exploded in the first two months, 40% of the remaining exploded by the half of the year, and at the end of the year, another 50% of the volcanoes that hadn't already erupted also exploded. How many mountains are still intact at the end of the year?

By the first two months, 20 / 100 * 200 = 40 mountains had erupted. The total number of mountains remaining after the first round of explosions is 200 - 40 = 160. When 40% of the remaining mountains exploded, the number of mountains that were still intact decreased by 40 / 100 * 160 = 64. The number of mountains that hadn't exploded after the second explosions is 160 - 64 = 96. When 50% of the mountains which were still intact exploded, the number of mountains that hadn't erupted was reduced by 50 / 100 * 96 = 48. At the end of the year, 96 - 48 = 48 mountains remained intact and hadn't exploded. The answer is 48.
