Question: A roll of 25 m wire weighs 5 kg. How much does a 75 m roll weigh?
Answer: Step-by-step reasoning process: 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.
So the answer is 15.

Question: The lights in Malcolm’s house are flickering, and he hopes that replacing all of his white lights with colored lights will make it stop. He buys 12 red lights, 3 times as many blue lights, and 6 green lights. If he still has 5 colored lights left to buy, how many white lights did Malcolm have initially?
Answer: Step-by-step reasoning process: Malcolm has bought 12 * 3 = 36 blue lights. This means he has bought a total of 12 + 36 + 6 = 54 colored lights. If he still needs to buy more lights, then he must have initially had 54 + 5 = 59 white lights.
So the answer is 59.

Question: Each frog needs to eat 30 flies per day to live. Each fish needs to eat 8 frogs per day to live. Each gharial needs to eat 15 fish a day to live. How many flies get eaten every day in this swamp if it has 9 gharials?
Answer: Step-by-step reasoning process: First find the number of fish the gharials need to eat: 9 gharials * 15 fish / gharial = 135 fish. Then find the number of frogs by multiplying that quantity by the number of frogs per fish: 135 fish * 8 frogs / fish = 1080 frogs. Then multiply the number of frogs by the number of flies each frog eats to find the number of flies: 1080 frogs * 30 flies / frog = 32,400.
So the answer is 32400.

Question: Shara borrowed money from her brother 6 months ago. She returned $10 per month to her brother. Currently, she was able to return half of the money she borrowed. How much will she still owe her brother 4 months from now?
Answer:
Step-by-step reasoning process: For 6 months, Shara was able to return $10 x 6 = $60 to her brother. Since she already returned half of the money, then this means she currently owes her brother $60. Four months from now, she will be able to pay an additional $10 x 4 = $40. Thus, she will still owe her brother $60 - $40 = $20 four months from now.
So the answer is 20.
