Calculate the amount of grain consumed by a bird weighing 2.5 kg per day, if it is known

Calculate the amount of grain consumed by a bird weighing 2.5 kg per day, if it is known that a bird eats 10 grams per unit of weight in one hour.

If we take into account that the unit of weight of a bird is 1 kg, then we find how much it eats in one hour:

10 gr * 2.5 = 25 gr of grain.

There are 24 hours in a day, so we find the mass of grain that the bird will eat during this time:

24 h * 25 gr = 600 gr of grain.

Answer: a bird weighing 2.5 kg will eat 600 g of grain per day.
