Q: 1,800 fish swim westward, 3,200 swim eastward, and 500 swim north. What is the number of fish left in the sea, if fishers catch 2/5 of the fish that swam eastward and 3/4 of the fish that swam westward?
A: When fishers caught 3 / 4 of the fish that swam westward, their total number reduced by 3 / 4 * 1800 fish = 1350. The total number of fish that remained from the total number that swam eastward is 1800 fish - 1350 fish = 450 fish. If fishers caught 2 / 5 of the fish that swam eastward, their total number reduced by 2 / 5 * 3200 fish = 1280 fish. 3200 fish - 1280 fish = 1920 fish remained in the sea from the number that swam westward. The total number of fish in the sea after fishers caught some is 500 of the number that went north + 450 of the fish that swam westward + 1920 of the fish that swam eastward = 2870 fish. The answer is 2870.
Question: Tom has a quarter as much money as Nataly. Nataly has three times as much money as Raquel. How much money do Tom, Raquel, and Nataly have combined if Raquel has $40?
Answer: If Nataly has 3 times as much money as Raquel, she has 3 * $40 = $120. Tom has 1 / 4 as much money as Nataly, so he has 1 / 4 * $120 = $30. Combined, the three have $30 + $120 + $40 = $190. The answer is 190.
[Question]Roy has 2 blue pens. He has twice as many black and 2 less than twice as many red than black pens. How many pens does Roy have in all?
[Answer]Roy has 2 x 2 = 4 black pens. Twice the number of black pens is 4 x 2 = 8. So, there are 8 - 2 = 6 red pens. Therefore, Roy has 2 + 6 + 4 = 12 pens in all. The answer is 12.
Q: Ross takes 17 breaths per minute by inhaling 5/9 liter of air to his lungs. What is the volume of air inhaled in 24 hours?
A: We have 60 minutes per hour. So, in 24 hours we have 60 * 24 = 1440 minutes. So, the volume of air Ross inhaled in 24 hours is: 17 breaths / minute * 5 / 9 L / breath * 1440 minutes = 122400 / 9 = 13600 liters. The volume of air inhaled is 13600 liters. The answer is 13600.
Question: Jimmy is setting up a garden. He has three plots: one plot for green beans, one plot for carrots, and one plot for corn. Each corn plant produces 5 times as many servings of veggies as each carrot, and each green bean plant produces half as many servings as each corn plant. If each carrot produces 4 servings of vegetables, and each plot has 9 plants, how many servings of vegetables is Jimmy growing?
Answer: First, find how many servings one corn plant produces by multiplying the number of carrot servings by 5: 4 servings * 5 = 20 servings. Then find how many servings one green bean plant produces by dividing the number of corn servings by two: 20 servings / 2 = 10 servings. Now multiply the number of servings per carrot plant by the number of carrot plants: 4 servings / plant * 9 plants = 36 servings. Do the same for corn: 20 servings / plant * 9 plants = 180 servings. And do the same for green beans: 10 servings / plant * 9 plants = 90 servings. Now add up the servings for all three types of plant: 36 servings + 180 servings + 90 servings = 306 servings. The answer is 306.
Q: Stefan, Vail, and Aiguo collected seashells. Stefan had 16 more seashells than Vail. Vail had 5 less than Aiguo. Aiguo had 20 seashells. How many seashells did the 3 children have in total?
A:
Aiguo = 20 shells. Vail = 20 - 5 = 15 shells. Stefan = 15 + 16 = 31 shells. Total = 20 + 15 + 31 = 66. The 3 children had 66 seashells altogether. The answer is 66.
