Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:
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. Final answer: 32400.
