On a farm, the ratio of horses to cows is 2:3. If there are a total of 100 animals, how many were horses?

The number of horses is 40

Solution:

Given that on a farm the ratio of horses to cows is 2 : 3

To find: Number of horses

From given ratio,

number of horses : number of cows = 2 : 3

Let the number of horses be 2x

Let the number of cows be 3x

Given that there are total of 100 animals

Therefore,

number of horses + number of cows = 100

2x + 3x = 100

5x = 100

x = 20

Therefore, number of horses = 2x = 2 (20) = 40

Thus there are 40 horses
