Answer:
original ratio of horses to cows:
5 horses to 30 cows = 5 : 30 = 1:6
After the farm gets more horses (without changing the number of cows), the farm has a ratio of 5:6, which must mean that the original number of horses is 5 times the original.
Therefore, there will be 5*5 = 25 horses and 30 cows after the new cows are added
