Final answer:
The number of bulls in a herd with a bull-to-cow ratio of 1:6 is one-seventh of the total number of animals in the herd, represented as x/7.
Step-by-step explanation:
In the scenario where the ratio of the number of bulls to cows is 1:6, we can express the number of bulls in terms of x, where x represents the total number of animals in the herd.
Let's define the number of bulls as B and the number of cows as C. Given the ratio B:C = 1:6, for every 7 animals in the herd (1 bull + 6 cows), there is 1 bull.
To find the number of bulls in terms of x, we divide the total number of animals by the sum of the parts of the ratio (1+6=7). So, the formula to find the number of bulls (B) is:
B = x / 7
Therefore, if x is the total number of animals in the herd, the number of bulls is one-seventh of x.
