If the dog eats two eyes and Oomyapeck eats 22 eyes, then there are a total of 2 + 22 = 24 eyes. With 2 eyes per fish, 24 eyes represent 24 / 2 = 12 fish. If they split that number of fish equally amongst the three of them, then each of them will be given 12 / 3 = 4 fish to eat.
The answer: 4
Reverse engineering the question: Ittymangnark and Kingnook are an Eskimo couple living in the most northern region of the Alaskan wilderness. Together, they live with their child, Oomyapeck. Every day Ittymangnark catches enough fish for the three of them to eat for the day and they split the fish equally between the three of them. But after they have split the fish, they give Oomyapeck all of the eyes, who gives two of the eyes to his dog and eats the rest himself. How many fish will each of them be given to eat if Oomyapeck eats 22 eyes in a day?
Reasoning and answer: 8 * 60 = 480 minutes are in the next 8 hours. Abigail builds 480 / 30 = 16 fences. Abigail will have built 10 + 16 = 26 fences in total.
The answer: 26
What was the question?
Question: Abigail built 10 fences. Each fence took her 30 minutes to build. If she builds fences for the next 8 hours, how many fences would she have built in total?
She gave out 50 - 8 = 42 stickers in total. She gave 4 * 5 = 20 stickers to her friends. She gave out 42 - 20 = 22 stickers to the rest of the class. This means there are 22 / 2 = 11 other students in the class. There are a total of 1 + 5 + 11 = 17 students in the class.
The answer: 17
Reverse engineering the question: Mary brought 50 stickers to class. She gave 4 stickers to each of her 5 friends. She gave everyone else in class two stickers each. If she has 8 stickers left over, how many students are in the class, including Mary?
Reasoning and answer: Let X be the amount of money Sarah has, so Bridget has X + 50 cents. We know that Sarah and Bridget combined have $3, or 300 cents, so X + X + 50 = 300. We therefore know that 2X = 250. So Sarah has 250 / 2 = 125 cents.
The answer: 125
What was the question?
Question: Bridge and Sarah have $3 between them. If Bridget has 50 cents more than Sarah, how many cents does Sarah have?
If the number of candles in the bedroom is twice the number in the living room, there are 20 / 2 = 10 candles in the living room. When Donovan brings in 20 more candles, the total number of candles becomes 10 + 20 + 20 = 50.
The answer: 50
Reverse engineering the question: Kalani has twenty candles in her bedroom, twice the number of candles in the living room. Donovan, her brother, brings in 20 more candles he bought from the candle shop. What's the total number of candles in the house?
Three dimes is equal to $.3 because 3 x .1 = .3. Seven nickels is equal to $.35 because 7 x .05 = .35. Each time he trades with dimes he lose $.05 because .3 - .25 = .05. Each time he traded with nickels he lost $.1 because .35 - .25 = .1. He lost $1 from trading with dimes because 20 x .05 = 1. He lost $2 from trading with nickels because 20 x .1 = 2. He lost $3 total because 1 + 2 = 3.
The answer: 3
Reverse engineering the question:
Mac loves the shape of quarters and is willing to trade money for them, even if he loses value. He tells his brother that he will trade him 3 dimes for a quarter or 7 nickels. He trades for 20 quarters with dimes and 20 quarters with nickels. How many dollars did Mac lose?
