Question: A boy has 12 oranges. He gives one-third of this number to his brother, one-fourth of the remainder to his friend and keeps the rest for himself. How many does his friend get?
Answer: Step-by-step reasoning process: He gives a third of 12 oranges to his brother which is 12 * (1 / 3) = 4 oranges. He has 12 - 4 = 8 oranges left. He gives a fourth of 8 oranges to his friend which is 8 * (1 / 4) = 2 oranges.
So the answer is 2.

Question: Four small panda bears and five bigger panda bears eat 25 pounds and 40 pounds of fresh bamboo sprouts every day, respectively. How many pounds of bamboo do the 9 pandas eat in a week?
Answer: Step-by-step reasoning process: The small panda bears eat a total of 4 x 25 = 100 pounds of bamboo every day. The bigger panda bears eat a total of 5 x 40 = 200 pounds of bamboo every day. So, the 9 pandas eat a total of 100 + 200 = 300 pounds of bamboo every day. Therefore, they eat a total of 300 x 7 = 2100 pounds in a week.
So the answer is 2100.

Question: Megan pays $16 for a shirt that costs $22 before sales. What is the amount of the discount?
Answer: Step-by-step reasoning process: Let x be the amount of the discount. We have, 22 - x = $16. We change the writing of the equation:. 22 - x + x = 16 + x. So, 22 = 16 + x. We then Remove 16 from both sides:. 22 - 16 = 16 + x - 16. So, 22 - 16 = x. So, the amount of the discount is x = $6.
So the answer is 6.

Question: Barbeck has two times as many guitars as Steve, but Davey has three times as many guitars as Barbeck. If there are 27 guitars altogether, how many guitars does Davey have?
Answer:
Step-by-step reasoning process: Let x = the number of guitars Steve has. Barbeck has 2x guitars, and Davey has 3 * 2x = 6x guitars. 2x + 6x + x = 27. 9x = 27. x = 27 / 9 = 3 so Steve has 3 guitars. Barbeck has 2 * 3 = 6 guitars. And Davey has 3 * 6 = 18 guitars.
So the answer is 18.
