Question: Tatuya, Ivanna, and Dorothy took a quiz together. Tatuya scored twice as much as Ivanna, and Ivanna scored 3/5 times as many marks as Dorothy. If Dorothy scored 90 marks, calculate the average marks scored by the three.
Answer: Step-by-step reasoning process: Since Dorothy scored 90 marks, and Ivanna scored 3 / 5 times as many marks, Ivanna scored 3 / 5 * 90 = 54 marks. Together, Dorothy and Ivanna scored a total of 54 + 90 = 144 marks. If Tayuta scored twice as many marks as Ivanna, she scored 2 * 54 = 108 marks. The total marks the three scored altogether is 108 + 144 = 252 marks. The average marks for the three are 252 / 3 = 84 marks.
So the answer is 84.

Question: Hakeem has always loved artichoke dip and plans to make it this weekend. He has $15 dollars to buy artichokes and can find the rest of the ingredients at home. It takes 3 artichokes to make 5 ounces of dip. How many ounces can he make if artichokes cost $1.25 each?
Answer: Step-by-step reasoning process: He can buy 12 artichokes because 15 / 1.25 = 12. Each artichoke makes 5 / 3 ounces of dip because there are 3 artichokes per 5 ounces. He can make 20 ounces of dip because 12 x (5 / 3) = 60 / 3 = 20.
So the answer is 20.

Question: The area of a forest is three times the area of the square-shaped street. If the street has a length of 100 meters on one side and the number of trees per square meter in the forest is 4, calculate the total number of trees in the forest.
Answer: Step-by-step reasoning process: Since the area of a square is sides squared, the area of the square - shaped street is 100 * 100 = 10000 square meters. The area of the forest is three times the area of the square - shaped street, a total of 3 * 10000 = 30000 square meters. If the number of trees per square meter in the forest is 4, there are 4 * 30000 = 120000 trees in the forest.
So the answer is 120000.

Question: Tim used to run 3 times a week but decided to add an extra 2 days a week. She runs 1 hour in the morning and 1 in the evening every day she runs. How many hours a week does she run now?
Answer:
Step-by-step reasoning process: He now runs 3 + 2 = 5 times a week. Each day he runs for 1 + 1 = 2 hours. So he runs 2 * 5 = 10 hours a week.
So the answer is 10.
