The ratio is 2:3 puppies to adult dogs, which means for every 2 puppies, there is 3 adult dogs.
Add the ratio together: 2+3 = 5
Divide total dogs by that total: 50 dogs / 5 = 10
Now multiply each number of the ratio by that to find the total number of each:
2 puppies x 10 = 20 total puppies.
3 adults x 10 = 30 total adult dogs.
