Q: The school principal decided that she wanted every class to have an equal number of boys and girls in each first-grade classroom. There are 4 classrooms. There are 56 boys and 44 girls. How many total students are in each classroom?
A: Each classroom will have 14 boys because 56 boys divided into 4 classrooms equals 14 boys per classroom. Each classroom will have 11 girls because 44 girls divided into 4 classrooms equals 11 girls per classroom. In total, each classroom will have 25 students because 14 boys plus 11 girls equals 25 total students. The answer is 25.
Question: The Lion King cost 10 million to make and earned 200 million at the box office. If it earned a profit that was half of what Star Wars made and Star Wars cost 25 million to make, how many millions did Star Wars earn?
Answer: The Lion King made 190 million in profit because 200 - 10 = 190. Star Wars made 380 in profit because 190 x 2 = 380. Star Wars earned 405 million because 25 + 380 = 405. The answer is 405.
[Question]Aubree saw 20 beavers and 40 chipmunks by a tree when going to school and scared them away when they saw her. While coming back from school, she realized the number of beavers had doubled and the number of chipmunks had decreased by 10. What's the total number of animals she saw that day?
[Answer]When going to school, she saw 40 + 20 = 60 animals. The number of beavers doubled to 20 * 2 = 40 beavers. The number of chipmunks decreased to 40 - 10 = 30 chipmunks. The total number of animals she saw on that day is 30 + 40 + 60 = 130 animals. The answer is 130.
Q: Out of 480 employees, 10% got a salary increase while 20% got a travel allowance increase. How many employees did not get any increase?
A: 480 x 10 / 100 = 48 employees got a salary increase. 480 x 20 / 100 = 96 employees got a travel allowance increase. So a total of 48 + 96 = 144 employees got an increase. Therefore, 480 - 144 = 336 employees did not get any increase. The answer is 336.
Question: Violet is planning a hike through the desert with her dog. Violet needs 800 ml of water per hour hiked and her dog needs 400 ml of water per hour. If Violet can carry 4.8 L of water, how many hours can she and her dog spend hiking?
Answer: First find the total amount of water Violet and her dog consume per hour: 800 ml + 400 ml = 1200 ml. Then divide that amount by 1000 ml / L to convert it to liters: 1200 ml / 1000 ml / L = 1.2 L. Then divide Violet's carrying capacity by the amount of water they drink per hour to find how many hours she can hike: 4.8 L / 1.2 L / hour = 4 hours. The answer is 4.
Q: There are 20 students in a class. Only one-fourth of the students stayed in the classroom while the rest went to the playground. Of those who went to the playground, one-third are boys. How many girls are there on the playground from this class?
A:
Out of the 20 students, 20 x 1 / 4 = 5 students stayed in the classroom. While 20 - 5 = 15 students went to the playground. Out of these 15 students, 15 x 1 / 3 = 5 are boys. Therefore, 15 - 5 = 10 girl students from this class are in the playground. The answer is 10.
