At an animal shelter there are 15dogs, 12 cats, 3 snakes and 5 parakeets. What percent of the number of cats is the number of dogs?

Total number of animals at the shelter = 15 + 12 + 3 + 5 = 35 animals.

Let the total number of animals be represented by 100%

There are 15 dogs and 12 cats so:

% Number of dogs = 15/35 x 100% = 42.86%

% Number of cats = 12/35 x 100% = 34.28%
