Question

There are twice as many cows as goats on a farm. All the cows and goats have a total of 1,116 legs. How many goats are there?

 

Answer 1

 All the animals have 4 legs, so first we find out how many animals there are by dividing 1,116 by 4.

 

so 1116/4=279

 

Now we also know that there are twice as many cows as goats. This means that 1/3 of the animals are goats. So we divide by the number of animals by 3.

 

279/3=93
