First find the number of tadpoles Trent released: 180 tadpoles * .75 = 135 tadpoles. Then subtract the number he let go from the total number to find the number of tadpoles he keeps: 180 tadpoles - 135 tadpoles = 45 tadpoles.
The answer: 45
Reverse engineering the question: Trent caught 180 tadpoles then let 75% of them go. How many did he keep?
Reasoning and answer: The total number of pages is 180 + 100 = 280 pages. The number of pages Yasna needs to read every day for two weeks is 280 / 14 = 20 pages.
The answer: 20
What was the question?
Question: Yasna has two books. One book is 180 pages long, and the other book is 100 pages long. If Yasna wants to finish both of the books in two weeks, how many pages will Yasna need to read every day, if she reads an equal number of pages each day?
A pound of coffee makes 40 cups of coffee, so 3 lbs. coffee * 40 cups of coffee per lb. = 120 cups of coffee. Angie drinks 3 cups of coffee a day, so she has enough coffee to last her 120 cups of coffee / 3 cups of coffee per day = 40 days.
The answer: 40
Reverse engineering the question: Angie bought 3 lbs. of coffee at the store today. Each lb. of coffee will brew about 40 cups of coffee. Angie drinks 3 cups of coffee every day. How many days will this coffee last her?
Reasoning and answer: Teddy has 7 + 8 = 15 pets in total. Ben has 9 + 7 = 16 dogs, which means he has 16 pets in total. Dave has 13 + 8 = 21 cats. Dave has 7 - 5 = 2 dogs. Dave has 21 + 2 = 23 pets in total. Combined, they have 15 + 16 + 23 = 54 pets in total.
The answer: 54
What was the question?
Question: Teddy has 7 dogs and 8 cats. Ben has 9 more dogs than Teddy, and Dave has 13 more cats and 5 less dogs than Teddy. How many pets do all of them have combined?
So far, Mary has paid back $15 + $23 = $38 of the credit. So she still needs to pay $100 - $38 = $62.
The answer: 62
Reverse engineering the question: Mary does her grocery shopping on Saturday. She does her shopping only at a specific store where she is allowed a credit of $100, which must be paid in full before her next shopping trip. That week she spent the full credit limit and paid $15 of it on Tuesday and $23 of it on Thursday. How much credit will Mary need to pay before her next shopping trip?
Grace can read 200 / 20 = 10 pages in 1 hour. So she can finish a 250 - page book in 250 / 10 = 25 hours.
The answer: 25
Reverse engineering the question:
Grace can read a 200-page book in 20 hours. How long would it take her to finish reading a 250-page book at this constant rate?
