The second tank is 48 / 2 = 24 gallons. Following her rule, Gail keeps 24 / 2 = 12 two - inch fish in the second tank. She keeps 48 / 3 = 16 fish in the first tank. If one fish in the first tank ate another, she would have 16 - 1 = 15 fish in the first tank. Thus, Gail would have 15 - 12 = 3 more fish in the first tank.
The answer: 3
Reverse engineering the question: Gail has two fish tanks. The first tank is twice the size of the second tank. There are 48 gallons of water in the first tank. She follows the rule of one gallon of water per inch of fish. If she keeps two-inch fish in the second tank and three-inch fish in the first tank, how many more fish would Gail have in the first tank than the second tank if one of the first tank fish eats another?


Reasoning and answer: Let x be the number of goats. Cows:4 + x. Pigs:2(4 + x) = 8 + 2x. Total:x + 4 + x + 8 + 2x = 56. 4x + 12 = 56. 4x = 44. x = 11 goats.
The answer: 11

Reasoning and answer: The bear gained 1 / 5 * 1000 = 200 pounds from berries. It gained 2 * 200 = 400 pounds from acorns. It still needed 1000 - 200 - 400 = 400 pounds. Thus, it gained 400 / 2 = 200 pounds from salmon. Therefore, the bear gained 400 - 200 = 200 pounds from small animals.
The answer: 200

Question: A bear is preparing to hibernate for the winter and needs to gain 1000 pounds. At the end of summer, the bear feasts on berries and small woodland animals. During autumn, it devours acorns and salmon. It gained a fifth of the weight it needed from berries during summer, and during autumn, it gained twice that amount from acorns. Salmon made up half of the remaining weight it had needed to gain. How many pounds did it gain eating small animals?


Reasoning and answer: Half of the number of Randy's mango trees is 60 / 2 = 30 trees. So Randy has 30 - 5 = 25 coconut trees. Therefore, Randy has 60 + 25 = 85 treeson his farm.
The answer: 85
