Q: A zoo has 16 pandas, paired into mates (in the same zoo). Only 25% of the panda couples get pregnant after mating. If they each have one baby, how many panda babies are born?
A: 2
Step-by-step reasoning process: First divide the number of pandas by 2 to find the number of couples: 16 pandas / 2 = 8 panda couples. Then multiply that number by 25% to find the number of babies: 8 panda couples * 25% = 2 panda babies.

Q: Anton has three times as many cards in his collection as Heike does. Ann has six times as many cards as Heike does. If Ann has 60 cards, how many more cards does Ann have more than Anton?
A: 30
Step-by-step reasoning process: If Ann has 60 cards, which is six times as many cards as Heike, Heike has 60 / 6 = 10 cards. Anton has three times as many cards in his collection as Heike does, and since Heike has 10 cards, Anton has 10 * 3 = 30 cards. Ann has 60 - 30 = 30 more cards than Anton.

Q: Tony wants to build the longest rope he possibly can, so he collects all the rope in his home. He finds an 8-foot rope, a 20-foot rope, three 2 foot ropes, and a 7-foot rope. each knot between the ropes makes him lose 1.2 foot per knot. How long is his rope when he's done tying them all together?
A: 35
Step-by-step reasoning process: The combined length of all the rope is 41 feet because 8 + 20 + (2 x 3) + 7 = 41. He loses 6 feet from the knots because 5 x 1.2 = 6. The final length is 35 feet because 41 - 6 = 35.

Q: Rhonda, Sally, and Diane are members of their school's track team. The three of them run the 600-meter relay race together. Rhonda runs the first 200 meters of the race, Sally runs the second 200 meters of the race, and Diane runs the final 200 meters of the race. Rhonda can run 200 meters in 24 seconds. Sally takes two seconds longer to run the same distance, while Diane can run 200 meters three seconds faster than Rhonda. How many seconds does it take for the three of them to run the 600-meter relay race?
A: 71
Step-by-step reasoning process: Sally takes 24 + 2 = 26 seconds. Diane takes 24 - 3 = 21 seconds. Thus, the three take 24 + 26 + 21 = 71 seconds to run the 600 - meter relay race.
