On an average day, a horse might drink 50 l, a sheep might drink 4 l, and a chicken might drink 200 male. how much water would a farm with 3 horses, 15 sheep and 12 chicken need for a day?

If one horse needs 50 L, then 3 horses will need 3*50, or 150 L. If one sheep needs 4 L, then 15 sheep will need 15*4, or 60 L. For chickens, I assume by 200 male you meant 200 mL. 200 mL is 0.2 L, so 12 chickens will need 12*0.2, or 2.4 L. Take the sum of all of the values and you get 150 + 60 + 2.4, or 212.4 L of water
