Q: Armand is playing a guessing game with his dad where he has to guess a number his dad is thinking of. His dad tells him that the number, when multiplied by 3, is three less than twice 51. What is the number?
A: 102 is twice 51 because 2 x 51 = 102. Three less than 102 is 99 because 102 - 3 = 99. The number is 33 because 99 / 3 = 33. The answer is 33.
Question: Pablo made 4 stacks of toy blocks. The first stack was 5 blocks tall. The second stack was 2 blocks taller than the first. The third stack was 5 blocks shorter than the second stack, and the last stack was 5 blocks taller than the third stack. How many toy blocks did Pablo use in all?
Answer: The number of blocks in the second stack is 5 + 2 = 7. The number of blocks in the third stack is 7 5 = 2. The number of blocks in the last stack is 2 + 5 = 7. Pablo used 5 + 7 + 2 + 7 = 21 toy blocks in all. The answer is 21.
[Question]Joan collects rocks. In her collection of rock samples, she had half as many gemstones as minerals yesterday. Today, she went on a rock collecting trip and found 6 more mineral samples. If she has 48 minerals now, how many gemstone samples does she have?
[Answer]Yesterday before her rock collecting trip, she had 48 - 6 = 42 mineral samples. She has 1 / 2 the number of gemstones, so she has 42 / 2 = 21 gemstone samples. The answer is 21.
Q: Cassie is trimming her pet's nails. She has four dogs and eight parrots. Each dog has four nails on each foot, and each parrot has three claws on each leg, except for one parrot who has an extra toe. How many nails does Cassie need to cut?
A: First, find the number of dog nails by multiplying the number of dogs by the number of nails on each leg and the number of legs on each dog: 4 dogs * 4 legs per dog * 4 nails per leg = 64 nails. Then do the same for parrots, ignoring the one parrot's extra toe for now: 8 parrots * 2 legs per parrot * 3 nails per leg = 48 nails. Now add one to the previous number because one parrot has an extra toe: 48 + 1 = 49 nails. Now add the number of nails from the parrots and the dog: 49 nails + 64 nails = 113 nails. The answer is 113.
Question: An airline company owns 5 airplanes. Every airplane they own has 20 rows with 7 seats in each row. Each airplane makes 2 flights a day. How many passengers can the airline company accommodate each day?
Answer: Each airplane has 20 x 7 = 140 seats. So, the 5 airplanes can accommodate a total of 140 x 5 = 700 passengers. Therefore, the airline company can accommodate 700 x 2 = 1400 passengers each day. The answer is 1400.
Q: Eighteen hours ago, Beth and I took 100 photographs of our project. Today, Beth and I will take 20% fewer photographs of the same project. If we were to take 300 photographs of the project, how many photographs would we take to reach the target?
A:
If you took 100 photographs of the project 18 hours ago, and today 20% few photographs have been taken, then 20 / 100 * 100 = 20 fewer photographs of the project have been taken today. The total number of photographs of the project that have been taken today is 100 - 20 = 80. So far, you've taken 80 + 100 = 180 photographs of the project. Since the target number of photographs is 300, the number of photographs that you need to take to reach the target is 300 - 180 = 120. The answer is 120.
