Question: James buys 3 CDs. Two of them are 1.5 hours each. The last one is twice that long. What is the combined length of the CDs?

[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.
Q: Carrie is wrapping three birthday presents. One present needs two square feet of wrapping paper to cover. The second present needs three-quarters of that amount. The third present needs the same amount as both other presents put together. How many square feet of wrapping paper does Carrie need for all three presents?
A: The second present needs 3 / 4 * 2 = 1 1 / 2 square feet of wrapping paper. The third present needs 2 + 1 1 / 2 = 3 1 / 2 square feet of wrapping paper. Therefore, Carrie needs 2 + 1 1 / 2 + 3 1 / 2 = 7 square feet of wrapping paper for all three presents. The answer is 7.
