Q: A roll of 25 m wire weighs 5 kg. How much does a 75 m roll weigh?
A: We know that the 75 m roll is three times bigger than the 25 m roll because 75 m / 25 m = 3. This means the 75 m roll weighs 3 times more than the 25 m roll: 5 kg * 3 = 15 Kg. The answer is 15.
Question: There are 2,000 kids in camp. If half of the kids are going to soccer camp, and 1/4 of the kids going to soccer camp are going to soccer camp in the morning, how many kids are going to soccer camp in the afternoon?
Answer: There are 2000 / 2 = 1000 kids going to soccer camp. There are 1000 / 4 = 250 kids going to soccer camp in the morning. There are 250 * 3 = 750 kids going to soccer camp in the afternoon. The answer is 750.
[Question]Mia is a student. In her final year, she spent 1/5 of her day watching TV and 1/4 of the time left on studying. How many minutes did she spend studying each day?
[Answer]If Mia spent 1 / 5 of her day watching TV, her remaining time in a day is 5 / 5 – 1 / 5 = 4 / 5 for other things. So, the time left is 24 * 4 / 5 = 19.2 hours. The time spent studying is 19.2 / 4 = 4.8 hours. In minutes, that is 4.8 * 60 = 288 minutes. The answer is 288.
Q: Toby is filling his swimming pool for the summer. The pool normally takes 50 hours to fill. He knows his hose runs at 100 gallons per hour. Water costs 1 cent for 10 gallons. How many dollars does it cost to fill the pool?
