d : c = 3 : 7
r : d = 2 : 5 or d : r = 5 : 2
then d:c = 15:35 and d:r = 15:6
so d:c:r = 15:6:35
let number of dogs be 15x , number of cats be 6x, and number of rabbits be 35x
then 15x + 6x + 35x = 1008
56x = 1008
x = 18
sub back into my definitions
An animal shelter has 1008 cats, dogs, and rabbits. The ratio of the number of dogs to the number of cats in the animal shelter is 3:7. The ratio of the number of rabbits to the number of dogs is 2:5. How many rabbits are there in the shelter? Show how to solve please.
