Question: Aliens and Martians have different numbers of limbs. Aliens have three arms and eight legs, while Martians have half as many legs and twice as many arms. How many more limbs will five aliens have than five Martians?
Answer: Martians have 2 * 3 = 6 arms each. They have 8 / 2 = 4 legs each. Five martians will have 5 * 6 + 5 * 4 = 30 + 20 = 50 limbs. Five aliens will have 5 * 3 + 5 * 8 = 15 + 40 = 55 limbs. Five aliens will have 55 - 50 = 5 more limbs than five Martians. The answer is 5.

[Question]The carousel at the fair has 3 blue horses, three times that many purple horses, twice as many green horses as purple horses, and 1/6th as many gold horses as green horses. How many horses are there total?
[Answer]First find how many purple horses there are: 3 blue horses * 3 purple / 1 blue = 9 purple horses. Then double that number to find how many green horses there are: 9 purple horses * 2 green / 1 purple = 18 green horses. Then divide the number of green horses by 6 to find the number of gold horses: 18 green horses / 6 green / 1 gold = 3 gold horses. Then add the number of horses of each color to find the total number of horses: 9 horses + 18 horses + 3 horses + 3 horses = 33 horses. The answer is 33.
[Question]Austin has 10 pairs of dress shoes he needs to polish over the weekend. If he has polished 45% of individual shoes, how many more shoes does he need to polish?
[Answer]
He has 10 pairs of shoes and each pair is made of 2 individual shoes for a total of 10 * 2 = 20 shoes. He has already polished 45% of the 20 individual shoes so he has polished .45 * 20 = 9 shoes. He has 20 shoes and has already polished 9 shoes so he has 20 - 9 = 11 more shoes to polish. The answer is 11.
