12/60 are puppies. 60 are the number of dogs, 12 is number of puppies.

If there are 1200 dogs, we focus on the 60. 1200/60= 20
Whatever we do to the denominator we do to the numerator, so since we can multiply 60 by 20 to get 1200; we need to multiply 12 by 20 to get the total number of dogs. Which is 240.
