A kennel has 125 dogs in total, some are puppies and some are adult dogs. The ratio of puppies to adult dogs is 1:4. How many adult dogs are there?

Answer 1

Since the ratio of puppies to adult dogs is 1:4 , there are a total of 5 dogs represented in the ratio - 1 puppy for 4 adult dogs.

Then we can create a pair of equivalent ratios for adult dogs to the total:

4 adult dogs = x adult dogs

5 total dogs 125 total dogs

You can multiply 5 by 25 to get 125 , so 4 times 25 is 100 adult dogs.

There will be 100 adult dogs out of the 125 total .
