Reasoning and answer: Dante needs half as many cups of flour to bake his chocolate cake as he needs eggs, meaning he needs 60 / 2 = 30 cups of flour for his recipe. Altogether, Dante needs 30 + 60 = 90 eggs and cups of flour for his recipe.
The answer: 90

Question: Dante needs half as many cups of flour to bake his chocolate cake as he needs eggs. If he uses 60 eggs in his recipe, calculate the total number of cups of flour and eggs that he uses altogether.


First find how much water fills the bathtub per hour: 40 ml / minute * 60 minutes / hour = 2400 ml / hour. Then subtract the water that evaporates to find the total amount of water added per hour: 2400 ml / hour - 200 ml / hour = 2200 ml / hour. Then multiply that amount by the number of hours to find the total amount of water in the tub: 2200 ml / hour * 9 hours = 19800 ml. Then find the number of milliliters in 12 liters: 12 liters * 1000 ml / liter = 12000 ml. Then subtract the water Jack removes from the total amount of water to find the remaining amount of water: 19800 ml - 12000 ml = 7800 ml.
The answer: 7800
Reverse engineering the question: Jack leaves his bathtub's faucet dripping at a rate of 40 ml/minute. Water evaporates from the bathtub at a rate of 200 ml/hour. If he leaves the water running for 9 hours, then dumps out 12 liters, how many milliliters of water are left in the bathtub?


Reasoning and answer: After Greg lent her $40, Tessa paid him back 40 / 2 = $20. So Tessa's debt was 40 - 20 = $20. Finally, she asked for $10 more, leaving the debt at 20 + 10 = $30.
The answer: 30

Question: Greg has lent his sister Tessa money on several occasions. Greg writes down all of his sister's debts in a notebook, the first time he lent her $40. A week later, Tessa paid him back half of her debt. A few days later she asked him for $10 more. How much does Tessa still owe Greg?


He rides his bike 6 + 7 = 13 miles to school and back every day. Therefore, Vins rode his bike 13 x 5 = 65 miles to school and back this week.
The answer: 65
Reverse engineering the question: Vins rides his bike 6 miles to school. He rides home a different route that is 7 miles long. This week, Vins rode to school and back 5 times. How many miles did Vins ride his bike this week?


Reasoning and answer: There are 5 x 1 / 2 = 10 halves of burgers made from 5 whole burgers. Era's first and second friends got 1 + 2 = 3 slices together. Her third and fourth friends got 3 + 3 = 6 slices together. Era's four friends got 3 + 6 = 9 slices. So, Era is left with 10 - 9 = 1 slice.
The answer: 1
What was the question?
Question: Era had 5 burgers for her and her 4 friends. She sliced each burger into halves. The first and second friends got 1 and 2 slices, respectively. Then the third and fourth friends got 3 slices each. How many slices of burgers are left for Era?


Reasoning and answer: Camden went swimming 16 / 4 = 4 times a week. Susannah went swimming 24 / 4 = 6 times a week. Susannah went 6 - 4 = 2 more times a week than Camden.
The answer: 2
What was the question?
Question:
Camden went swimming 16 times in March and Susannah went 24 times. If the number of times they went throughout the month was divided equally among 4 weeks, how many more times a week did Susannah swim than Camden?
