Question: A herring has 40 oz of fat, an eel 20 oz, and a pike 10 more oz of fat than an eel. If Ellianna cooked and served 40 fish of each type, calculate how many ounces of fat she served.
Answer: Step-by-step reasoning process: Ellianna cooking 40 herrings with 40 oz of fat each gives her 40 * 40 = 1600 oz of fat. If Ellianna also cooked 40 eels with 20 oz of fat each, she got 40 * 20 = 800 0z of fat. All the herrings and eels together have a total fat content of 1600 + 800 = 2400 oz of fat. A pike, with 10 more oz of fat than an eel, has 10 + 20 = 30 oz of fat. Cooking 40 pikes gives 40 * 30 = 1200 oz of fat. Since Ellianna cooked all the fish, she had 1200 + 2400 = 3600 oz of fat in her serving.
So the answer is 3600.

Question: Justin needs to collect one flower for each classmate that is in his 2nd-grade class. It takes him on average 10 minutes to find a flower he likes. He has been gathering for 2 hours. Assuming he has lost 3 of the flowers he initially gathered, how many more minutes does he need to look if he has 30 classmates?
Answer: Step-by-step reasoning process: If he gathers for 2 hours, the number of minutes gathering is 2 * 60 minutes per hour = 120 minutes of gathering flowers. Gathering for 120 minutes / 10 minutes per flower = 12 flowers gathered. If he gathers 12 flowers initially but lost 3, he has 12 - 3 = 9 flowers gathered and kept. Since he has 30 classmates total and has 9 flowers, he needs to gather 30 - 9 = 21 more flowers. Assuming it takes 10 minutes per flower, it will take him 10 * 21 = 210 minutes to gather the remaining 21 flowers needed.
So the answer is 210.

Question: Of 96 oranges, half were ripe. If 1/4 of the ripe oranges were eaten and 1/8 of the unripe oranges were eaten, how many were left eaten in total?
Answer: Step-by-step reasoning process: There were 96 / 2 = 48 ripe oranges. 48 / 4 = 12 ripe oranges were eaten. 48 / 8 = 6 unripe oranges were eaten. There were 12 + 6 = 18 oranges eaten in total. There were 96 - 18 = 78 oranges left uneaten.
So the answer is 78.

Question: Joan has 2 hours to get all her music practice done. She spends 30 minutes on the piano, 25 minutes writing music on her computer, and 38 minutes reading about the history of the piano. Her final work is to use a special finger exerciser. How much time does she have left to use this?
Answer:
Step-by-step reasoning process: She has 120 minutes to practice because 2 x 60 = 120. She has already spent 93 minutes on her work because 30 + 25 + 38 = 93. She has 27 minutes to use on finger exercise because 120 - 93 = 27.
So the answer is 27.
