My question is: 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? Your thoughts:
The total ratio of cattle on the farm is 10 + 27 = 37. Since the fraction that represents bulls from the total ratio is 27 / 37, the number of bulls on the farm is 27 / 37 * 555 = 405. The final answer: 405.
