### Instruction: The ratio of cows to bulls in a barn is 10:27. If there are 555 cattle on the farm, how many bulls are on the farm?### Response: The total ratio of cattle on the farm is 10+27 = 37
The fraction that represents bulls from the total ratio is 27/37, and since there are 555 cattle on the farm, the number of bulls is 27/37*555 = 405
The answer is 405
